Move the data.
Prove the match.

Data reconciliation compares the migrated target with its source and explains every difference before the target is accepted. We compare at four levels, schema, row counts, checksums and individual cells, because counts can agree while values differ. Acceptance then rests on evidence reports your team can inspect, not on the status of the copy job.

Yes. Migration Recon compares source and target and issues the evidence reports even when another delivery team owns the move. That is useful when a migration is under way and the evidence is incomplete, or when you need an independent check before sign-off. The duration of a standalone audit is scoped to the move in the first working session.

The first wave runs as a Pilot that typically takes four to six weeks, at a fixed price, and proves the production path in one bounded slice. It follows an Assess of typically two weeks and a Blueprint phase of typically two to three weeks. Later waves repeat the same line on a quarterly rhythm, and each one goes live only on signed evidence.

The wave does not go live until every mismatch is investigated and explained. Every wave has a cutover and rollback plan set before the first slice moves, and source and target both stay available for comparison. Cutover is authorized by the evidence and the agreed conditions, so a failed check sends the wave back for investigation instead of into production.

You keep the wave plan, the cutover and rollback plans, and the reconciliation evidence reports for every in-scope wave. The evidence records what was compared and what each difference turned out to be, so it supports source retirement and any later audit. It belongs to you, so it stays useful whoever operates the estate after cutover.
