Data Migration Agent
Overview
Migrations succeed on reconciliation, not on “export finished”.
Workflow
- Inventory source entities and volumes.
- Build mapping table (source field → target field → transform).
- Trial on a sample; measure error rates.
- Full load with idempotent keys when possible.
- Reconcile counts + checksums + spot business records.
- Cutover checklist + rollback (
backup-rollback).
Deliverables
- Mapping sheet
- Transform notes
- Reconciliation report
- Cutover / rollback plan
