Microsoft Dynamics GP
is being discontinued
Here's what that means for your business and what
to do about it.
Mainstream support for Dynamics GP ended in 2025. Extended support runs through 2029. After that, no security patches, no compliance updates, no new features. The window to migrate on your own terms is open now. Once it closes, you'll be migrating under pressure.

What GP customers worry about most, and the honest answers
After 25 years of GP implementations and migrations, we’ve heard every version of these concerns. The good news is that every single one of them has a clean answer, and none of them are reasons to stay on a platform that’s running out of road.
"We'll lose our historical data"
You won’t. Transaction history, vendor records, customer accounts, and financial data all migrate to Business Central. A structured data migration plan ensures nothing is left behind.
"Our team will have to relearn everything"
Business Central was built by Microsoft with GP users in mind. The logic is familiar. We include structured training as part of every implementation so your team hits the ground running on day one.
"It'll disrupt our month-end close"
We plan every go-live around your financial calendar. Most implementations are timed to land at the start of a new fiscal period so disruption to close cycles is minimal or zero.
"It'll cost more than we can justify"
We provide fixed-scope proposals so you know the full cost before committing. Most GP customers find that the cost of migration is lower than the cost of staying — once you factor in the risk of running unsupported software.
How a GP to Business Central migration actually works
Here’s exactly what to expect when you work with Centrum. No surprises, no moving targets.
Discovery and assessment
We map your current GP environment — your chart of accounts, customizations, integrations, and data structure. This is where we identify complexity before it becomes a problem.
Fixed-scope proposal
You receive a detailed scope of work with a fixed price and a realistic timeline. No estimates that balloon mid-project.
Data migration and configuration
Your GP data migrates cleanly to Business Central. We configure the system to match your workflows and chart of accounts — not a generic template.
Parallel testing
our team runs both systems simultaneously for a defined period so you can verify everything before GP is retired.
Go-live and training
We go live on a date that works with your financial calendar. Structured training ensures your team is confident from day one.
Ongoing support
Post go-live support is built into every engagement. We’re not gone the day you go live — we stay involved through your first close cycle and beyond.

Frequently asked questions about
Dynamics GP migration
Is Microsoft Dynamics GP being discontinued?
Yes. Microsoft ended mainstream support for Dynamics GP in 2025. Extended support continues through 2029, after which GP will run without security patches, compliance updates, or any new development. Businesses still on GP after 2029 face meaningful compliance and security risk.
What is the best replacement for Microsoft Dynamics GP?
Microsoft Dynamics 365 Business Central is the most natural and most commonly recommended migration path for GP customers. It was designed by Microsoft with GP users in mind, preserves familiar financial architecture, and adds cloud scalability, real-time reporting, and AI capabilities that GP was never built to deliver.
How long does a GP to Business Central migration take?
Most mid-market GP migrations run between 3 and 6 months depending on the complexity of your environment, the number of customizations, and the volume of historical data being migrated. A well-scoped project with an experienced partner rarely runs over that window.
Will I lose my historical data when migrating from GP?
No. Your historical financial data, vendor records, customer accounts, and transaction history all migrate to Business Central. The key is a structured data migration strategy — something our team plans and executes as a core part of every GP migration engagement.
How much does it cost to migrate from Dynamics GP to Business Central?
Migration costs vary based on the size of your organization, the complexity of your GP environment, and the scope of customizations and integrations involved. Most mid-market migrations fall between $40,000 and $120,000 in professional services. We provide fixed-scope proposals so you know the full cost before the project starts.
Can we keep running GP past 2029?
Technically yes — Microsoft won’t remotely disable the software. But running GP after extended support ends means operating without security patches or compliance updates, which creates real risk for any business handling sensitive financial data or operating in a regulated environment. Most businesses treat 2029 as a hard deadline.
