Microsoft will end Dynamics GP support on December 31, 2029, with security updates until April 30, 2031, and GP 2016 already lost support in July 2026. The replacement options, the integrations that make ERP moves slow, and how to use the time well.
In September 2024 Microsoft announced the end of Dynamics GP after more than four decades. Product enhancements, tax updates and technical support end on December 31, 2029 (moved from an earlier September date); security updates continue until April 30, 2031. GP 2016 and GP 2016 R2 already reached end of support on July 14, 2026.

Dynamics 365 Business Central: Microsoft's intended destination, with migration tooling from GP.
Another cloud ERP (NetSuite, Sage Intacct, Acumatica and others): worth evaluating if GP was chosen long ago and the business has changed.
Stay on the latest GP until 2029 on supported infrastructure, and use the time to clean data and simplify processes before moving.
The ERP itself is rarely the slow part. Integrations are: the e-commerce feed, the warehouse system, the reports someone built in SQL Server Reporting Services against GP's tables, the nightly exports to the bank. Each has to be found, understood and rebuilt against a new data model and API.
Inventory every integration and report that touches the GP database, including the ones built directly in SQL.
Move reporting onto a separate data store fed from GP now, so reports survive the ERP change unchanged.
Archive closed years instead of migrating them.
Choose the replacement by mid-2027, so the move happens with time to spare rather than in the last quarter of 2029.
