A migration is a trust exercise. We treat reversibility as the primary design constraint: every cutover we run has a tested rollback path that can be executed under pressure.
Dual-write, then verify
Change data capture keeps old and new systems in lockstep while an automated reconciler compares them row by row until divergence is zero.
Rehearse the cutover
We run the switch against production-scale data repeatedly until the timing is boring. The real cutover should be the least eventful one.
Keep the door open
The legacy system stays warm and writable behind a feature flag until you are satisfied. Rolling back is a decision, not an incident.
