For many businesses, the ERP server in the back office has been a quiet, reliable part of the furniture for years. It runs Dynamics GP, NAV or an on-premises version of Dynamics 365, the finance team knows it well, and as long as nobody touches it, it keeps working.
The trouble is that the world around that server has changed. Staff expect to work from anywhere. Customers expect faster answers. Cyber attacks are more frequent and more expensive. And the most useful new tools, from AI assistants to live dashboards, are built for the cloud first, and often for the cloud only.
In this article, we’ll explain why so many businesses are moving their Microsoft Dynamics systems from on-premises servers to Dynamics 365 in the cloud, and what they actually gain from the move.
Why Migrate D365 from On-Premises?
There are two kinds of reasons: the ones pushing you away from on-premises, and the ones pulling you towards the cloud.
What is pushing businesses away from on-premises
Microsoft has been clear that its future investment in business applications is in the cloud. For customers of its older on-premises ERP products, the support clock is running down:
- Dynamics GP: product updates, tax updates and support end on December 31, 2029, with security updates only until April 30, 2031. Our guide to Dynamics GP end of support explains what this means in detail.
- Dynamics NAV: every version is out of mainstream support, and the remaining extended support for NAV 2018 ends in January 2028. After that, NAV customers will receive no fixes of any kind.
- On-premises versions of Dynamics 365: these still exist, but new features, especially Copilot and AI, arrive in the cloud versions first or only.
Staying on an unsupported system means no tax or regulatory updates, no security fixes and a shrinking pool of people who know how to support it.
What is pulling businesses towards the cloud
The bigger reason to move is what the cloud makes possible. AI tools that suggest bank matches or draft emails, dashboards that update in real time, apps that let a warehouse team or a sales rep work from a phone: these all depend on your data living in a modern, connected cloud platform. An on-premises ERP can be linked to some of them, but only with extra effort, extra cost and extra things that can break.
When your data sits in separate systems that don’t talk to each other, decisions slow down. Businesses that keep putting off the move tend to find themselves spending more to maintain old technology while their competitors spend less and move faster.
For most small and mid-sized businesses on GP or NAV, the natural cloud destination is Dynamics 365 Business Central.
Key Benefits of a Microsoft Dynamics 365 On-Premises to Cloud Migration
The benefits you see will depend on your starting point and your goals. A distributor with three warehouses will value different things from a professional services firm with staff working from home. But broadly, a well-planned move to Dynamics 365 in the cloud gives you a secure, connected platform that grows with your business rather than holding it back.
Here are the benefits our clients notice most.
Bring All Data Into One Central Location
In many on-premises setups, information is spread across the ERP, a separate CRM, spreadsheets on shared drives and reports that someone exports every Monday. By the time a manager sees the numbers, they are already out of date.
Dynamics 365 in the cloud brings finance, sales, purchasing, inventory and service data together on one platform. Because it connects directly with Power BI, you can build dashboards that update automatically and share them with anyone who needs them, whether they are in the office, at a customer site or in another country.
That single view makes a real difference. You can see which products and customers are most profitable, spot cash flow problems early, plan stock levels more accurately and track projects against budget as they happen. And with Copilot built in, users can ask questions about their data in plain language instead of waiting for a report to be built.
When everyone works from the same live data, fewer decisions are made on guesswork.
Cost Savings
On-premises systems carry a lot of hidden costs. There are the servers themselves, which need replacing every few years. There are SQL Server and Windows licences, backup systems, disaster recovery plans, security software and the IT hours spent keeping it all running. And every few years there is an upgrade project that can cost as much as a small implementation.
With Dynamics 365 in the cloud, Microsoft looks after the infrastructure, backups, security patches and updates. You pay a predictable monthly subscription per user, and your system moves to the latest version automatically.
The savings are not only on hardware. A cloud system usually means:
- No more large, one-off upgrade projects
- Less time spent by IT on maintenance and troubleshooting
- Lower spending on disaster recovery and backup tools
- Fewer third-party add-ons, because many features are now standard
It is worth being honest here: a cloud subscription is not always cheaper than an on-premises licence line by line. But when you compare the full cost of ownership over five years, including servers, IT time and upgrades, the cloud usually comes out ahead. We are happy to work through the numbers for your business before you decide.
Better Security
Many business owners still feel their data is safer on a server they can see in their own building. In practice, the opposite is usually true.
Keeping an on-premises system secure means applying every patch on time, monitoring for threats around the clock, managing firewalls, testing backups and training staff, all without gaps. Most small and mid-sized businesses simply do not have the people or budget to do all of that well. One missed update or one exposed server is enough for an attacker to get in.
Microsoft spends billions on security every year and employs thousands of specialists to protect its cloud. Dynamics 365 in the cloud benefits from:
- Data encryption, both while stored and while moving between systems
- Sign-in through Microsoft Entra ID, with multi-factor authentication and conditional access
- Detailed, role-based permissions so people only see what they need
- Continuous monitoring and automatic security updates
- Built-in backups and geographic redundancy, which reduce the impact of ransomware or hardware failure
- Compliance with major international standards, which helps with audits and customer requirements
Security is still a shared responsibility. You decide who has access and how strong their passwords are. But the heavy lifting of protecting the platform moves to Microsoft.
Optimize IT Resources
When your ERP moves to the cloud, the servers that hosted it can be retired. So can much of the routine work that went with them: patching, backups, SQL maintenance and weekend upgrade windows.
That frees your IT team to work on things that add value to the business, such as:
- Automating repetitive tasks with Power Automate, such as approvals, reminders and document routing
- Building simple apps with Power Apps for field staff or warehouse teams
- Improving reporting and analytics
- Strengthening security across the rest of the business
- Supporting new projects, locations or sales channels
For smaller businesses without a dedicated IT department, the benefit is even clearer. You no longer depend on one person, or one outside contractor, to keep a critical server alive.
It does take some planning to make the most of this. Before you migrate, it is worth listing what your IT team currently spends time on and deciding where you want that time to go afterwards.
Anywhere Access
This is often the first benefit people notice. With Dynamics 365 in the cloud, your team can use the system from a laptop, tablet or phone, from any location, through a normal web browser or the mobile app. There are no VPN connections to set up and no remote desktop sessions that drop in the middle of a task.
That matters even if most of your staff work in the office:
- Sales reps can check stock, prices and customer history while visiting a client
- Managers can approve purchase orders or expenses while travelling
- Warehouse and field staff can update records on the spot instead of on paper
- Teams in different branches or countries all see the same information at the same time
- Accountants and auditors can be given secure, limited access without extra infrastructure
When everyone works from the same live system, fewer mistakes are made, fewer calls are needed to check information, and customers get answers faster.
Final Thoughts
Some businesses move to the cloud because they see the opportunity: better insight, lower costs and tools that help them grow. Others move because staying where they are has become too risky. Both are valid reasons, and the destination is the same.
What matters most is how the move is planned. A good migration looks carefully at your data, your processes, your customizations and your people, and it moves at a pace your business can manage.
