Why it matters
Dynamics GP still works, and it will keep receiving security updates into 2031. But tax updates and technical support end with 2029, Microsoft’s new development goes into Business Central, and every year adds more history and more workarounds to migrate.
The deadline is only half of it. GP keeps a server, a SQL Server database, backups, a VPN, and somebody’s weekends tied up. Moving to Business Central turns that into a subscription Microsoft runs: updates arrive on their own, finance works from anywhere, and the data sits on the same platform as Microsoft 365, Power BI, and Copilot instead of behind a firewall.
The organizations that move early pick their cutover date and retire their hardware on their own schedule. The ones that wait share partners and timelines with everyone else.
