Migrate Data Between Tools

Migrate records from a source tool/format to a destination tool/format — CRM to CRM, spreadsheet to app, JSON export to a new API — with a field mapping, value transforms, and a reconciliation that proves nothing was lost or corrupted. Locks the source→destination field map, the transform/normalization rules, and the reconciliation criteria FIRST, then builds the extract-transform-load with a dry-run preview, then verifies record counts match, key fields round-trip, and a diff report flags any mismatch. Mapping-and-reconciliation-before-load is the discipline that makes a migration trustworthy rather than a one-shot leap of faith.

How it runs

3Verify the migrationReviewercounts reconcile, fields round-trip, diff clean
4EvaluateReviewerGrade the deliverable against every acceptance criterion. All pass → finish; any fail → loop back and fix the gap.
5FinishDeveloperAll acceptance criteria met. Stamp a short summary and report DONE.

Say something like "migrate data between tools" or "move my CRM data" or "import an export into another app" or "convert and load records" or "migrate a spreadsheet to an app" in chat to start it.
