Dynamics GP is on-premises ERP in its final support era: Microsoft ended new customer sales and has published end-of-support timelines, so GP receives no new functional investment. Business Central is its cloud successor, with the same accounting concepts, a modern web and mobile client, native Microsoft 365 integration and continuous updates. For GP customers, the question is no longer whether to move but how to sequence customizations and history.
Dexterity customizations and heavily modified windows do not port. They get re-implemented as extensions, replaced by native capability, or dropped because the process changed since they were written. Cataloging them honestly is the single biggest determinant of project cost.
Integrations built on direct SQL access must be rebuilt against APIs. This is usually an improvement — it removes the fragility of writing straight into tables — but it is real work that has to be budgeted.

Common questions
Microsoft has ended new customer sales and published end-of-support dates, so plan on a defined runway rather than an open one. Treat the migration as a scheduled program, not an emergency, and confirm current dates against Microsoft's lifecycle documentation.
For a period, yes — commonly by entity or by site. Parallel operation of the same entity for long stretches doubles the workload and should be time-boxed.
Not directly. Management reporting is rebuilt in Power BI or native financial reporting, which is why report rebuild belongs in the pre-go-live scope.
