Microsoft has officially announced that Dynamics GP (Great Plains) product support will end on December 31, 2029. While that date may feel far off, the reality is that the impact of GP’s sunset is already being felt by organizations today.
Security risks are increasing. Integrations are becoming harder to maintain. Customizations are more expensive to support. And internal teams are spending more time troubleshooting instead of moving the business forward.
If you’re currently running Dynamics GP, the question is no longer if you should plan a migration, but when and how.
This guide breaks down a realistic ERP migration checklist and timeline, based on i-Tech’s experience supporting more than 200 successful ERP migrations.
What Dynamics GP End-of-Support Means for Your Business
As GP moves closer to end-of-support, organizations remaining on the platform face growing challenges, including:
- Diminishing product updates and long-term viability
- Increasing cybersecurity and compliance risks
- Rising license, customization, and support costs
- Limited automation and integration capabilities
- Longer troubleshooting and resolution times
In many cases, maintaining GP becomes more costly and riskier than moving to a modern, cloud-based ERP designed to scale with your business.
How Long Does an ERP Migration Take?
ERP migrations are not one-size-fits-all. Timeline length depends on factors like company size, data volume, customizations, integrations, and internal availability.
Lower-complexity organizations typically complete a migration in about 6 months. These organizations often have smaller teams, limited customizations, fewer integrations, and higher internal project availability.
Higher-complexity organizations may require up to 18 months, especially if they operate across multiple entities or locations, rely heavily on custom code, or face regulatory and compliance constraints.
The key takeaway: successful migrations are planned not rushed.
