Data migration off legacy platforms

Migration consulting for businesses stuck on legacy software: we plan and execute the move to modern SaaS or custom platforms, and prove with reconciliation reports that every record made the trip.

  • data migration
  • legacy systems
  • reconciliation
  • cutover planning

The problem

The software is old, unsupported, or holding the business back, but the data inside it is the reason nobody dares to leave. Years of customers, transactions, and documents sit in formats the new platform does not understand, and a botched cutover means losing history the business runs on.

What we built

  • An audit of the legacy data: what exists, what is duplicated, what maps where
  • Field-by-field mapping and cleanup before anything moves
  • Staged migration with dry runs against a copy of production, not the real thing
  • Reconciliation reports so record counts and totals match on both sides
  • A cutover plan with a tested rollback, and the old system kept readable until the new one is verified

What changed

Clients landed on their new platforms with their history intact and an audit trail proving it, instead of the big-bang weekend cutover they were dreading.
