What it covers

Incremental, resumable sync — Millions of records moved in slices with conflict handling and a reconciliation report against the source's own counts — 1.3M records with Velocify.
Typed API layer — REST or GraphQL in front of the legacy system, with OAuth, rate limits and contract tests so integrations survive changes underneath.
Rehearsed cutover — Dry runs on a copy, a numbered runbook, and a rollback path tested before the real window.

How we work

Sync first (read-only), shadow-run the new reads against the old, then cut writes over — with rollback at every step.
