Microsoft migration services

Great Plains ends in 2030. Your financials need a modern home.

We assess your GP environment, map your customizations and historical data, and migrate you to Dynamics 365 Business Central without disrupting your close cycle.

The timeline is fixed

Microsoft will end support for Dynamics GP after 2028 (mainstream) and 2030 (extended). After that: no security patches, no regulatory updates, no tax table changes, no support. Every company still running GP needs to move.

2026

You are here. GP migrations typically take 4 to 12 months depending on customizations and data volume.

2028

Mainstream support ends. No new feature updates. Migration demand spikes and partner availability tightens.

2030

Extended support ends. No security patches. Unsupported GP becomes a compliance and audit risk.

How we do it

Assessment first. We scope before we build.

1

Environment assessment

We inventory every GP module, customization, integration, report, and SmartList you run. Dexterity modifications, VBA scripts, eConnect integrations, third-party ISV add-ons. You get a full picture of your actual footprint, not just what's in the license.

2

Migration plan

Each module and customization gets mapped to its Business Central equivalent. We flag what transfers natively, what needs an AppSource replacement, what requires custom development, and what you should retire. Historical data migration gets its own plan.

3

Build and cutover

We migrate in phases, aligned to your fiscal calendar. Each module is configured, tested with your data, and validated by your team before go-live. We time the cutover so it never falls during a close.

What we hear most

"We have 15 years of history in GP."

We migrate the historical data you need for reporting and compliance. Data that's only needed for reference goes into a searchable archive so it stays accessible without bloating Business Central.

"We've heavily customized GP."

That's exactly why we assess first. Many GP customizations exist because GP lacked something Business Central handles natively. We identify which customizations transfer, which ones you no longer need, and which require new development.

"We can't disrupt month-end or year-end close."

We plan the cutover around your fiscal calendar. Parallel operation during the transition period means your team validates Business Central against GP results before anyone flips the switch.

Start with an assessment

We'll scope your GP environment and tell you exactly what the migration looks like: timeline, cost drivers, and risk areas. No commitment past the assessment.
