THE CHALLENGE
An ageing on-premise data warehouse was expensive to run, slow to query and close to end of support.
WHAT WE DID
- 01Designed a target architecture on AWS
- 02Migrated incrementally with weekly demos
- 03Ran old and new platforms in parallel and reconciled every number
- 04Handed over with full documentation and training
“The parallel run meant we switched over with total confidence. Not a single number moved.”
