Should Small Businesses Move Everything to the Cloud? What I Look at Before Recommending a Cloud Migration
Updated: Aug 25
Updated August 2026: I originally wrote this article based on my experience helping small businesses evaluate and implement cloud migrations. I have updated it to reflect current Microsoft 365 capabilities, newer security and compliance considerations, and additional experience I have gained implementing both fully cloud based and hybrid environments for small businesses.
When small business owners talk to me about moving to the cloud, the conversation often starts with a simple question: Should we move everything?
My answer is usually that I need to understand the business before I can answer that. Moving a small business to the cloud can mean a lot of different things. It might mean replacing a local file server with SharePoint and OneDrive. It could mean moving email into Microsoft 365 or Google Workspace, moving computers away from a traditional local domain and into cloud based identity and device management, replacing an application that currently runs on a server, or doing some combination of those things. In other cases, the better answer may be a hybrid environment where some parts of the business move to cloud services while an application or server stays on premises.
I have worked through both kinds of environments, including full cloud migrations and hybrid designs. What I have learned is that the technology decision makes a lot more sense once I stop asking, “Can this move to the cloud?” and start asking, “How does this business actually work, and what happens if we change this?”

What Does Moving a Small Business to the Cloud Actually Mean?
“Moving to the cloud” is one of those phrases that can sound much more specific than it really is. Two business owners can use those exact words and be talking about completely different projects. One company may have an aging Windows server that is primarily being used for shared files and user accounts. Another may have a server running an ERP, accounting platform or specialized line of business application that employees depend on every day. A third company may already be using Microsoft 365 for email and OneDrive but still have company files scattered between local computers, a NAS, SharePoint, personal cloud accounts and an old server nobody is quite sure they still need.
Those businesses should not automatically receive the same recommendation. Before I start talking about products, I want to know what the existing systems actually do. I want to understand where the company's information is stored, how employees authenticate, what applications they use, how they work remotely, what they print and scan, what happens during an internet outage, what backup and recovery currently look like, and whether regulatory, contractual or cyber insurance requirements affect the environment.
Sometimes the answer is that most of the business can move into cloud services. Sometimes there is a good reason to keep something local. Sometimes the biggest problem is that nobody has a complete picture of the existing environment yet.
Should a Small Business Move Everything to the Cloud?
Not necessarily. There are plenty of situations where moving email, identity, company files and device management into cloud services can make sense for a small business. Employees may need easier remote access, the company may be replacing aging infrastructure, or the business may no longer have a compelling reason to maintain a traditional file server.
That does not mean every application and every workload automatically belongs there. An older accounting application, ERP, database, specialized industry platform or equipment integration may still have a legitimate reason to remain on premises. Large files, connectivity limitations, application dependencies, recovery requirements and the way employees actually work can all influence the decision.
That is why I look at cloud, on premises and hybrid environments as options rather than treating one of them as the goal.
What Will Moving to the Cloud Actually Look Like for My Employees?
One of the best questions I have been asked during a cloud planning conversation was not about licensing, servers or security controls. The business owner wanted to know what the proposed environment would actually look like to an employee.
The company was considering moving email, user identities and files into Microsoft cloud services while keeping an important line of business application on an existing on premises server. The owner's questions were practical. Could an employee sign into the computer and get to email? Where would the company files be? Could the employee still open the application running on the local server? Could they print?
Those are exactly the kinds of questions I want a business owner asking.
I could explain the general workflow from experience because I had already implemented a similar hybrid operating model for another small business. The environments and requirements were different, but the basic employee experience was familiar. Employees could sign into Entra ID joined and managed computers, use Microsoft 365 and SharePoint for their everyday cloud resources, and connect through Remote Desktop when they needed an application that remained on an on premises server.
From the employee's perspective, that can be fairly straightforward. They sign into the computer, open Outlook, access the files they are supposed to use and connect to the other application when they need it. Behind that experience, however, there can be a lot of planning involving identity, permissions, security, networking, remote access, backup and application dependencies. A migration can be technically successful and still create unnecessary frustration if nobody has thought about how people actually do their jobs.
The Small Things Employees Do Every Day Matter
I learned this during another cloud migration when something as ordinary as scanning documents became an important part of the project. When a business has spent years working from a traditional shared drive, employees develop routines around it. A multifunction printer may scan directly into a network folder. An employee may open the same mapped drive every morning without even thinking about where the files physically live. An application may export documents to a particular folder. Someone working remotely may have a completely different process from the person sitting in the office.
Moving the files is only part of the project. The workflow still has to work afterward.
This is why I want to understand those everyday processes before the migration. Where do documents come from? Where do they go? Who needs them? What applications interact with those folders? Which permissions are intentional and which ones simply accumulated over the years? Microsoft also recommends assessing existing file environments, planning the destination structure and considering user onboarding as part of a SharePoint and OneDrive migration. A traditional Windows file share and SharePoint do not handle every permission scenario in exactly the same way, so simply copying years of folders into SharePoint is not how I want to approach the project.
Can I Use Microsoft 365 and Still Keep a Server On Premises?
Yes. For some businesses, a hybrid environment can be the right answer. A company might use Microsoft 365 for email, SharePoint and OneDrive for company files, Entra ID for cloud identity and Intune for device management while still maintaining an on premises server for an ERP, accounting platform or another application that is not being moved.
That does not automatically make the environment better or worse than going fully cloud based. It simply means the design needs to account for both environments. The important questions become how employees authenticate, how they reach the application that remains local, what information passes between systems, how remote access works, what happens during an outage, how everything is backed up and which systems need to be monitored and documented.
This is one reason I do not like making cloud decisions from a product checklist. I want the architecture to follow the business requirements rather than forcing the business to change simply because a particular technology is available.
Is SharePoint a Replacement for a File Server?
Sometimes it can be part of replacing a traditional file server, but I would not treat SharePoint as a file server with a different address. SharePoint and OneDrive are designed around cloud based collaboration, access and Microsoft 365 integration. A traditional Windows file server is built around a different model. Folder structures, permissions, sharing, synchronization and employee workflows need to be evaluated rather than assuming everything will behave exactly as it did on the old shared drive.
Before moving files, I want to understand what is there. That includes who needs access, whether old data still needs to be migrated, whether permissions still make sense, whether outside users have access to anything, and whether an application, scanner or other process depends on a particular folder structure. A migration can also be a good opportunity to stop carrying years of unnecessary data and outdated permissions into a new environment simply because they existed in the old one.
“Moving files to the cloud is the easy part. Deciding who should have access to them and how that access should be protected is where the planning matters.”SNL-Tech Services
Who Should Be Able to Access Your Cloud Files, and From What Device?
This is particularly important when SharePoint is going to contain sensitive or regulated information. Moving a folder into SharePoint does not mean every employee should have access to it, and it certainly does not mean every computer an employee can find should automatically be allowed to download company information.
Before I move business files into SharePoint, I want to understand who legitimately needs access and how that access should be structured. Accounting, HR, management, project teams and other areas of the company may need different access. Depending on the environment, Microsoft 365 groups, security groups, SharePoint permissions and other controls can be used to build that structure. The exact design depends on the business rather than one universal folder and permissions template.
The device matters too. Microsoft supports Conditional Access and SharePoint controls that can restrict access from unmanaged devices. Depending on the business, its licensing and the security requirements, an unmanaged device can potentially be limited to browser based access with actions such as downloading, printing and synchronization restricted, or access can be blocked altogether. For a business handling sensitive information, that can be an important difference between allowing an employee to work and allowing company data to be copied onto a computer the business does not manage.
None of this means that every business needs exactly the same Conditional Access policies or SharePoint configuration. It means I want the access model designed intentionally before the business begins relying on SharePoint as a major repository for company information.
Location Can Be Part of the Access Decision Too
Device security is not the only context I consider. Location can also be useful when it makes sense for the business. Entra Conditional Access can use named locations and country or region information as part of an access policy.
For many of the small businesses I manage, if the company operates in the United States and has no legitimate reason for employees to sign in from other countries, I generally block access from outside the United States. If the company has an employee legitimately working from another country, someone is traveling internationally or another business need exists, I account for that and make the appropriate exception. That is my security approach based on the way the particular business operates, not a blanket Microsoft, HIPAA or CMMC requirement.
I also do not treat location restrictions as a replacement for MFA, managed devices, Conditional Access, monitoring or good identity security. Location is another signal that can help reduce unnecessary exposure when it fits the business.
Why Does This Matter If Your Business Wants to Use AI Later?
There is another reason I want SharePoint permissions and access under control before moving large amounts of company information into it. More businesses are beginning to consider Microsoft Copilot and other AI tools that can work with information already available inside their business environment.
AI does not fix an existing permissions problem. If an employee already has access to information they should not have been able to see, making that information easier to find does not correct the underlying access. This is why I would rather identify excessive permissions, old access, unmanaged sharing and other problems before a business starts connecting AI more deeply to its information.
I go much deeper into this in AI Governance for Small Business and in my Microsoft 365 Tenant Security Review. The important point for a cloud migration is that decisions about permissions, sharing and data organization today can affect what the business is ready to do with AI later. Your Microsoft 365 security and AI governance content already reinforces this same connection.
Is the Cloud More Secure Than an On Premises Server?
I would not answer that with a blanket yes or no. Cloud providers can take responsibility for substantial portions of the underlying infrastructure, but moving into a cloud service does not remove the business's responsibility for security. Identity, authentication, permissions, devices, external sharing, administrative access, applications and configuration still matter.
Microsoft 365 is a good example. Having Microsoft 365 licensing and having Microsoft 365 properly configured and managed are two different things. I have reviewed environments that were functioning normally from the employees' perspective while important security and management issues existed underneath them.
That is one of the reasons I offer a Microsoft 365 Audit, also described as a Microsoft 365 Tenant Security Review. I want to look at how the tenant is actually licensed, configured, secured and being used rather than assume the environment is ready simply because Outlook, OneDrive and SharePoint work. Your existing Microsoft 365 security content already goes deeper into what those configuration decisions can include.
The same general principle applies to businesses using Google Workspace. If Google Workspace is going to become a larger part of the company's cloud strategy, the existing environment should be reviewed based on Google's controls and the way the business actually uses the platform rather than assuming Microsoft 365 and Google Workspace should be secured identically.
Is My Data Automatically Backed Up Because It Is in the Cloud?
Cloud storage, version history, retention, recovery and backup are related, but they are not all the same thing. Microsoft 365 includes native recovery and retention capabilities across services such as SharePoint and OneDrive, and Microsoft also offers Microsoft 365 Backup. The more useful question for a business owner is not simply, “Does Microsoft have a backup feature?” It is what does my business expect to be able to recover, from what type of event, how far back and how quickly?
What happens if an employee deletes an important folder? What happens if nobody notices missing information for several months? What happens if files are changed or encrypted in bulk? What happens when an employee leaves? What information is included in the company's backup and recovery strategy, and has anyone actually verified that the recovery process works?
Those questions should be answered before the business depends more heavily on cloud services, not after something has already gone wrong.
What Happens If the Internet Goes Down?
Internet connectivity becomes more important as more of the business depends on cloud services. That does not make the cloud automatically a bad choice. It means connectivity becomes part of business continuity planning.
I want to understand what an outage would actually stop. Would employees lose access to company files? Is the phone system cloud based? Can the business process payments? Can employees reach the application they use all day? Can some work continue offline? How long can the company reasonably operate without its primary connection?
For some businesses, secondary internet or cellular failover makes sense. For another company, the cost may not be justified. The decision should be based on what downtime actually means to that business.
Is Moving to the Cloud Cheaper Than Replacing a Server?
Sometimes. Not always.
Comparing the purchase price of a server to the monthly cost of Microsoft 365 or another cloud service does not give you the full picture. A realistic comparison can include server hardware, warranties, operating systems, backup, power, maintenance, remote access, security tools, IT management, cloud licensing, migration costs, storage and connectivity.
There are also operational costs that are harder to put into a spreadsheet. What does it cost when employees cannot access files remotely? What does it cost to keep an aging server running because one application still depends on it? What does it cost when nobody knows how the environment is configured and every technology change becomes a troubleshooting exercise?
I would rather show a business owner those tradeoffs than tell them the cloud is automatically cheaper.
What If My Business Is Regulated?
Being in a regulated industry does not automatically mean the business cannot use cloud services. It does mean the decision needs another layer of review.
For healthcare organizations subject to HIPAA, HHS permits covered entities and business associates to use cloud services for electronic protected health information when the applicable HIPAA requirements are satisfied. Depending on the relationship and how ePHI is handled, a cloud service provider may be a business associate and an appropriate Business Associate Agreement may be required. The organization still has its own responsibilities for risk analysis, safeguards and the way the environment is configured and used.
For government contractors, the questions are different. Before deciding where information belongs, the business needs to understand what information it handles, whether FCI or CUI is involved, which systems process, store or transmit that information, and what contractual or CMMC requirements apply. A cloud platform should not be treated as automatically making the business compliant simply because the vendor offers a government focused service.
Financial businesses subject to requirements such as the FTC Safeguards Rule may have another set of obligations around protecting customer information and overseeing service providers. The FTC's rule requires covered financial institutions to maintain safeguards appropriate to their circumstances and the sensitivity of the information involved.
For regulated businesses in particular, the access questions we discussed earlier become extremely important. Who can reach the information? From what devices? How is access authenticated? Can information be downloaded to an unmanaged device? How is access removed? What gets logged? The exact answers depend on the requirements that apply to that business, but moving regulated information into the cloud does not eliminate the need to answer them.
The important distinction is that cloud is an architecture decision, not a compliance designation.
My role is to handle the technical implementation, security configuration, IT management and documentation that fall within my work. When a compliance consultant, assessor, attorney, insurance professional or another specialist is responsible for interpreting a separate requirement, I work with that information rather than presenting my technical work as a substitute for their role.
What About Businesses That Are Not Heavily Regulated?
The same planning still matters. A landscaping company, law firm, veterinary office, construction company, nonprofit, professional services company or other small business may not have the same regulatory requirements as a medical practice or defense contractor, but it still has information worth protecting. Customer records, employee information, contracts, financial information, credentials, email and business files all matter.
Cyber insurance can add another layer. A business may be asked about MFA, encryption, endpoint protection, backups, remote access, email security and other controls even when a regulation is not driving those requirements. I go deeper into those questions in Cyber Insurance Requirements for Small Businesses, including why I want to verify what is actually configured before telling a business how I would answer a technical insurance question.
That is why I do not divide businesses into “regulated, so security matters” and “not regulated, so it doesn't.” The requirements may be different, but every business needs to understand what it is protecting and what happens when technology fails.
What If I Do Not Really Know What My Business Has Today?
This is more common than many business owners think. Technology accumulates over time. One company installed the firewall. Someone else set up Microsoft 365. A previous employee created a shared folder. Another vendor configured the backup. Computers were added as people were hired. An application has been running on a server for years, but nobody is completely sure what else depends on that server.
Eventually the owner knows that everything seems to work, but does not necessarily have a complete picture of how it all fits together.
That is exactly where an IT Baseline Assessment can make sense. Before making a major technology decision, I can take a broader look at the company's environment so we understand what is actually there, how the business is using it and what needs attention. You do not need to know whether you need SharePoint, a new server, a hybrid environment or a full cloud migration before doing the assessment. Figuring that out can be part of the reason for establishing the baseline in the first place.
If the larger environment is already understood and the question is specifically about Microsoft 365, a Microsoft 365 Audit may be the more appropriate starting point. If the business relies on Google Workspace, I can focus the review on that platform instead. The point is to start with the question the business actually needs answered rather than prescribe the same assessment to everyone.
A Cloud Migration Can Be Part of a Much Bigger Technology Change
Sometimes the cloud is only one piece of what needs to change. I have worked with businesses where moving toward Microsoft 365 was part of a broader modernization effort involving aging infrastructure, endpoint security, user accounts, file access, networking and documentation. That kind of project is very different from simply moving a folder from a server into SharePoint.
I walk through one of those projects in From Outdated to Compliant. The larger lesson is that cloud adoption should not be evaluated in isolation when the technology environment underneath it also needs attention.
I have also completed full cloud migrations where the goal was to move away from the traditional local server and domain environment altogether. That is a different story, and one I plan to cover separately because the migration process and what changed for the employees deserve more detail than makes sense inside this article.
What Should I Ask Before Moving My Small Business to the Cloud?
Before approving a cloud migration, I would want a business owner to be able to get clear answers to questions like these:
What systems, applications and cloud services do we actually use today?
Where is company information currently stored?
Which systems genuinely need to move, and is there anything that should stay on premises?
What will employees experience differently after the migration?
How will employees access email, files and applications?
What happens to printers, scanners and existing workflows?
Who should have access to the files after they move?
What devices should be allowed to access or download company information?
What happens to existing file permissions and outside sharing?
How will remote employees work?
What happens if the internet connection goes down?
What are the backup and recovery requirements?
What security controls should be configured before the new environment becomes operational?
Are there regulatory, contractual, cyber insurance or client requirements that affect the design?
What will the migration cost beyond the monthly cloud subscription?
How will the new environment be documented, monitored and managed after the migration?
If the business plans to use AI later, are its data, permissions and access controls ready for that?
If nobody can answer those questions yet, that does not mean the business should abandon the idea of moving to the cloud. It means there is more discovery to do before making the decision.
So, Should Your Small Business Move to the Cloud?
Maybe. But I would not make that decision simply because the server is old, another business moved to Microsoft 365, or somebody said everything belongs in the cloud now.
I would start by understanding what your business has, how your employees work, what information needs to be protected, which applications matter, what happens during an outage and what requirements apply to your environment. Then I would decide what should move, what should stay and what needs to be fixed before either happens.
For some businesses, that leads to a largely cloud based environment. For others, the right answer is hybrid. Sometimes the first step is not migration at all. It is finally documenting and understanding the environment the business already has.
That is why I like starting with the problem rather than the product.
Not Sure What Your Business Is Ready For?
You do not need to decide that your company is moving completely to the cloud before talking to me. If you are not sure what systems you have, where your files live, what applications depend on the local network or how a migration would affect your employees, an IT Baseline Assessment may be the better starting point.
If Microsoft 365 is already central to the business and you want to understand how the tenant is currently configured before putting more of the company into it, my Microsoft 365 Audit takes a deeper look at that environment. For businesses using Google Workspace, I also offer a Google Workspace Audit focused on that platform.
The goal is to understand where you are first. Once we have that, we can make a much better decision about where your technology should go next.
Frequently Asked Questions
Does a small business need to move everything to the cloud?
No. Some businesses are good candidates for moving most of their environment into cloud services, while others benefit from keeping certain applications or systems on premises. The decision should be based on applications, employee workflows, connectivity, security, recovery requirements and any regulatory or contractual requirements that apply.
Can Microsoft 365 replace my local server?
It depends on what the server currently does. If it primarily provides file storage and user access, Microsoft 365 services may be able to replace many of those functions. If the server runs an ERP, accounting system, database or another specialized application, that workload needs to be evaluated separately.
Can we move our files to the cloud but keep an application on premises?
Yes. A hybrid environment can allow employees to use cloud identities, email and file services while continuing to access an application running on an on premises server. The environment still needs to be designed around authentication, security, remote access, backup, connectivity and the way employees actually work.
Is SharePoint the same as a file server?
No. SharePoint can replace some of the functions businesses traditionally use a file server for, but it uses a different model for collaboration, sharing, synchronization and permissions. Existing file structures, access and workflows should be assessed before migration rather than assuming the old shared drive can simply be copied into SharePoint unchanged.
Can I stop unmanaged computers from accessing SharePoint files?
Microsoft provides controls that can restrict SharePoint and OneDrive access from unmanaged devices. Depending on the configuration, licensing and business requirements, access can potentially be limited to the browser with restrictions on downloading and synchronization, or blocked. The appropriate approach depends on the company's data, users and security requirements.
Is Microsoft 365 secure by default?
Microsoft provides a broad set of security capabilities, but the configuration appropriate for a particular business depends on its licensing, users, devices, data and risks. Owning Microsoft 365 licensing does not by itself tell you whether the tenant is configured or managed appropriately. I cover this in more detail in my Microsoft 365 Tenant Security Review.
Is cloud storage the same as backup?
Not necessarily. Cloud platforms can provide versioning, retention and recovery capabilities, and separate backup services may also be available. A business should define what information needs to be recoverable, how far back recovery may need to go and how quickly information needs to be restored.
Can a HIPAA regulated business use cloud services?
Yes, cloud services can be used in a HIPAA regulated environment when the applicable HIPAA requirements are satisfied. The organization still needs to understand where ePHI is created, received, maintained or transmitted, what responsibilities belong to service providers, whether appropriate Business Associate Agreements are required and what safeguards apply.
Can a government contractor use cloud services?
Potentially. The answer depends on the information being handled and the requirements that apply to the contract and systems. A contractor should understand whether FCI or CUI is involved and which systems process, store or transmit that information before deciding where those workloads belong.
What is an IT Baseline Assessment?
An SNL-Tech Services IT Baseline Assessment takes a broader look at a company's technology environment so the business can understand what it has, how it is being used and what needs attention. It can be particularly useful when a business is considering a major technology change but does not have current documentation or a complete understanding of the existing environment.
What is the difference between an IT Baseline Assessment and a Microsoft 365 Audit?
The IT Baseline Assessment looks at the broader IT environment. A Microsoft 365 Audit focuses specifically on the Microsoft 365 environment and how it is licensed, configured, secured and being used. Which one makes sense depends on the question the business is trying to answer.
What if my business uses Google Workspace instead of Microsoft 365?
SNL-Tech Services also offers a Google Workspace Audit for businesses that need a focused review of their Google environment. If the larger concern is that the company does not have a clear picture of its overall technology environment, the IT Baseline Assessment may be the better starting point.
