Legacy system migration guide
How to replace spreadsheets and ageing tools without a big-bang ERP programme.
Start with the workflow teams use daily
Replace the highest-pain spreadsheets and manual handoffs first. Accounting and legacy ERP can often stay while a new operational layer ships in phases.
Map integrations before you build
List systems of record, export paths, and which data must stay in sync. Integration planning in discovery prevents a second migration project later.
Plan for adoption, not just go-live
Role-based training, a supported launch window, and stabilisation after the first module goes live matter as much as the technical cutover.
