The starting point
Migrate an existing warehouse
The current warehouse is difficult to maintain, but reports and teams depend on its behavior.
Map dependencies, migrate a bounded workload and compare data and report outputs before phased cutover.
Illustrative project scenario—not a client case study.
Decisions we work through
- Historical data and transformation parity
- Parallel-run acceptance criteria
- Consumer cutover and rollback
Agreed reports reconcile between old and new datasets, with intentional differences documented.
