Data Migration Risk Calculator
Row count, downtime tolerance, and rollback complexity - a rough risk level and a mitigation checklist.
Mitigation checklist for medium risk
- Run a full dry-run migration on a staging copy of the data first
- Have a tested rollback script ready before starting
- Schedule during a lower-traffic window and notify affected teams
- Take a verified backup and confirm it restores correctly before starting
A planning aid based on simple rule-of-thumb scoring, not a guarantee - every migration is different. Use this to prompt the right conversations, not as a final verdict.
