Cutover and rollback template
Checkpoints, evidence and decision owners for the window.
| Checkpoint | Evidence reviewed | Decision owner and action on failure |
|---|---|---|
| Pre-cutover readiness | Change freeze, communications, access, source recovery position, roles | Release authority: proceed, defer or reduce scope |
| Final consistent point | Final backup, extract watermark or replication position | Migration lead: verify or stop |
| Abort milestone | Defined progress point reached by the pre-agreed time, measured against timed rewind duration | Named abort authority, acting alone: continue or rewind |
| Target readiness | Load or catch-up complete, validation thresholds met, security checks | Data and security owners: accept or remediate |
| Business release | Critical business and workload checks accepted | Business owner: release or extend validation |
| Rollback boundary | The explicit condition beyond which return is unsafe | Named authority: consciously accept the crossing |
| Handover | Monitoring, support and defect ownership accepted | Service owner: accept or retain migration control |
Record times, evidence, participants and decisions as cutover proceeds. In the rollback section, describe how the source is preserved, how target writes are handled, who is informed, the recovery sequence and the latest safe time for the decision.
