Quick Answer:
Microsoft is phasing out Dynamics GP on a fixed timeline:
- April 1, 2025: Perpetual license sales ended
- April 1, 2026: Subscription license sales end
- December 31, 2029: End of mainstream support, including tax and regulatory updates
- April 30, 2031: Security patches stop
Microsoft's Bridge to Cloud 3 promotion offers a 30% discount on Dynamics 365 cloud licenses through December 2027.
The software suite now called Microsoft Dynamics GP has been a workhorse for mid-sized businesses since the early 1990s. Originally developed by Great Plains Software (and later acquired by Microsoft) it became one of the most widely adopted financial management and ERP platforms for small and mid-market organizations. Thousands upon thousands of companies have relied on Dynamics GP for their accounting, inventory, payroll, and HR processes for decades.
At long last, its era is winding down. Microsoft has published a clear sunset timeline for Dynamics GP, and the key milestones are no longer years away.
The first major cutoff, the end of new perpetual license sales, has already passed on April 1, 2025. New subscription sales close imminently – at time of writing – on April 1, 2026. From there, the clock runs toward the end of mainstream support at the end of 2029 and the final security update in April 2031. This may sound like a long time; at the speed of business IT adoption, it will be here before you know it.
If your organization is still running GP, the question isn't whether to migrate – that decision has been made for you. You can, however, decide where you migrate to, how, and when.
In this blog, we’ll help you answer those questions.
Waiting to Migrate Off GP Is Riskier Than It Looks
The 2031 security cutoff may feel distant, but practical risks will start compounding well before that. Once mainstream support ends in 2029, GP stops receiving key features like tax table updates, regulatory fixes, and product enhancements. For organizations that rely on GP for payroll or financial reporting in regulated industries, the 2029 date is the date that really matters. You’ll technically be able to keep the software running, but staying in compliance will A, require lots of manual work from your team, and B, get increasingly hard to keep up with.
There's also a less obvious pressure: the talent market. As Microsoft shifts investment toward Business Central and Dynamics 365 Finance, key talent – GP consultants, ISVs, and third-party add-on vendors, just to name a few – will follow. The firms and specialists who know GP inside and out are increasingly pivoting their practices toward cloud platforms.
That means the longer you wait to start a migration, the smaller your pool of experienced help becomes, and the more likely you are to be competing for that help with every other organization that also put it off.
The Real Cost of "Running It Until It Dies"
You may have already paid for the license, but staying on GP past its support date is hardly “free.” Aging on-premises servers need maintenance, and custom integrations with modern platforms like CRMs, ecommerce systems, or cloud-based payroll providers get progressively more brittle and expensive to maintain. In a hybrid work environment, requiring a VPN connection just to approve a purchase order is the kind of friction that quietly drains productivity across an organization while ensuring that your top talent will be updating their resumes and looking for a new position that won’t make them jump through hoops to do their jobs.
Life After GP: Where to Migrate To
For most GP customers, the natural landing spot is Microsoft Dynamics 365 Business Central.
This makes sense, of course; Business Central is the platform Microsoft has explicitly positioned as GP's successor for both small and mid-market companies, and, consequently, it offers the most straightforward migration tooling. If you were looking for a platform with a dedicated cloud migration tool that handles things like table-by-table data replication from your on-premises GP database, Business Central is your go-to destination.
In addition to this, Microsoft also publishes a migration assessment tool at bcmigrationassessments.com that can flag potential issues based on your specific GP configuration before you commit to anything.
That said, Business Central isn't the only option. Organizations with more complex, multi-entity operations or enterprise-scale requirements may find that Dynamics 365 Finance and Supply Chain Management is a better fit. And some companies use the GP sunset as an opportunity to evaluate non-Microsoft platforms entirely. The right answer depends on your transaction volumes, customization footprint, integration landscape, and growth plans.
Bridge to Cloud 3
If you're leaning toward staying in the Microsoft ecosystem, the timing works in your favor. Microsoft's Bridge to Cloud 3 (BTC3) promotion, which launched at the start of 2026 and runs through the end of 2027, offers a 30% discount on Dynamics 365 cloud licenses locked in for a three-year term. Critically, BTC3 also includes dual access rights, meaning you can keep running your on-premises GP environment while you stand up and validate your new cloud environment in parallel. That removes one of the biggest historical pain points of ERP migrations: paying full price for two systems simultaneously during the transition.
Start Planning Your Dynamics GP Migration Now
Most GP-to-Business Central migrations take six to twelve months, depending on factors like data volume, customizations, and third-party add-ons. Either way, with the clock ticking – not to mention things like training and prep time – you're looking at a project that rewards an early start. The BTC3 enrollment window closes at the end of 2027, but the best implementation partners are already booking out.
IES has deep experience in both Dynamics GP and Business Central. We can help you assess your current environment, determine the right migration path, take advantage of BTC3 pricing, and manage the transition from start to finish. Get in touch to start the conversation.
