What data warehouse migration means when we build it

A warehouse migration succeeds or fails on reconciliation. If a director's number changes by 0.3% on cutover day, trust in the whole platform is gone.

Every engagement opens with a measurement: the cycle time, the cost per transaction, or the error rate we are being asked to move.

Built by engineers who ship production systems, not by a practice that subcontracts the build. We hand over with runbooks, tests and a team that knows how it works, not a dependency.

What is included

  • Inventory of every table, job and downstream consumer
  • Query translation with behaviour differences documented
  • Row-level and aggregate reconciliation between old and new
  • Dual running until the numbers agree
  • Staged cutover by consumer group
  • Cost model comparing before and after

Who this is for

We usually work with data leaders, CIOs and analytics managers, the people who own the outcome rather than the tooling decision.

Questions we get asked

How do you avoid breaking reports?

Row-level and aggregate reconciliation between old and new, plus dual running until the numbers agree. Consumers move in stages, never all at once.

Which warehouse should we move to?

It depends on workload and existing cloud. We model cost against your real query patterns rather than list pricing, and sometimes the answer is to stay.

How long does it take?

Driven by the number of downstream consumers far more than data volume. The inventory in week one gives a realistic estimate.
