Data migration
Changing systems is frightening for a sensible reason: between the old one and the new one sit the years of information your company runs on. A migration done properly shows up as nobody noticing it happened.
Free reviewWhen you need this
- You are changing systems and the history worries you more than the new system does.
- You have data spread across several places that should live in one.
- You are carrying a database with years of duplicates and fields nobody uses.
- You cannot afford to stop the operation for a whole weekend.
What it includes
- A map of what is there, what comes across and what gets left behind.
- Cleaning and consolidation before moving, not after.
- Verification that everything arrived, with the numbers matching on both sides.
- A rollback plan, in case it has to be undone.
How we do it
Nothing gets switched off until the new system runs on real data and the figures match the old one. That is the criterion for closing the phase, and until it is met nothing moves on.
Five phases, each with its own acceptance criteriaQuestions about this service
Do we have to stop while it migrates?
Almost never. The normal approach is to move the bulk with everything running and leave only the last stretch of changes for the cutover.
How do we know nothing was lost?
By matching figures on both sides: totals, counts and samples checked one by one. If something does not match, it does not close.
