Data migration services
Moving off old systems without losing a row. We map what you have, move it in rehearsed steps, and compare old and new until the numbers match, before anyone switches over.
What’s included
Legacy databases to modern platforms
Old SQL Server, Oracle or MySQL systems moved to PostgreSQL or a cloud warehouse.
On-premise to cloud
Data and the jobs around it moved to AWS, Azure or Google Cloud.
Spreadsheets into databases
Years of Excel files turned into tables with rules and owners.
Reconciliation
Counts, totals and samples compared between old and new, in writing.
Cut-over planning
A rehearsed switch-over, with a way back if something’s wrong.

Questions about data migration
Will there be downtime?
Usually very little. We rehearse the move first and plan the switch for a quiet window, so the final cut-over is short.
How do we know nothing was lost?
Every migration ends with a reconciliation report comparing counts, totals and sampled records between the old and new systems.
