Building a Realistic GP to Business Central Migration Timeline
Migrating from Microsoft Dynamics GP to Business Central isn’t a quick system upgrade — it’s a full ERP implementation that impacts every part of your business. With Microsoft support for GP ending in 2029, now is the time to start planning your move. Companies that start early gain a major advantage: more time to plan, test, train, and tailor the system for long-term success.
The Pitfall: Underestimating Timeline and Internal Resource Needs
One of the most common mistakes in GP migrations is assuming it can be done in a few short weeks with minimal internal effort. In reality, a successful migration requires dedicated time from your team — especially finance, operations, and IT. When companies underestimate this, they often face:
- Overextended staff balancing daily work with migration tasks.
- Rushed testing and training that lead to user frustration and rework.
- Unexpected costs and delays from unrealistic scheduling.
- Missed opportunities to improve processes before go-live.
The Solution: Start Early and Plan Strategically
A realistic timeline is one that accounts for your team’s workload, your business cycle, and the level of change needed. TrinSoft helps organizations build a tailored migration plan that balances urgency with structure. We guide you through each phase — from discovery to post-go-live support — with clear milestones, defined roles, and proactive communication.
Our typical phased approach includes:
- Discovery & Planning – Establish goals, assess data, and define scope.
- System Build & Migration – Configure Business Central and migrate critical data.
- Testing & Validation – Confirm accuracy and fine-tune key processes.
- Training & Go-Live – Equip your team for success with role-based training.
- Post-Go-Live Optimization – Adjust and refine as your team gets comfortable.
This structured plan gives you the flexibility to manage internal resources while maintaining momentum toward your go-live date.
