A database migration without a tested rollback plan is a risk waiting to surface.
Before moving production traffic to GBase Database or any other target, define the exit strategy in advance.
1. Define Rollback Triggers
Use measurable conditions, not opinions:
- Dual-write data difference > 0 for N minutes
- P95 latency exceeds baseline by 10% for M minutes
- Error rate exceeds the predefined threshold
- Replication or data consistency checks fail
2. Define Rollback Steps
A practical rollback plan should include:
- Freeze writes on the new system
- Route application traffic back to the source
- Verify reverse synchronization
- Confirm transaction completeness
- Resume normal traffic only after validation
3. Assign Ownership & Timing
Every rollback step needs:
- A named owner
- A defined time budget
- A clear success condition
The complete database migration rollback process must fit inside the maintenance window.
4. Rehearse Before Go-Live
A rollback plan that has never been tested is only documentation.
Run a full drill before the GBase Database cutover. Record the actual recovery time and fix any step that exceeds the target.
Rule: If the rollback drill exceeds the maintenance window, change the plan—not the clock.
