Data Migration Integrity

Risk Statement: Data corruption or loss occurs due to checksum drift during migration.

Triggers / Signals:

• Checksum mismatches between source and destination
• High error rates during data imports
• Validation failures on imported records
• Anomalies in row counts across environments

Likelihood: Medium

Impact: High – corrupted data can lead to system instability and costly rework.

Mitigations:

• Implement checksums before and after migration to detect drift
• Perform incremental migration with validation at each step
• Maintain a robust backup plan and rollback strategy
• Run dry runs and cross-environment comparisons prior to cutover

Owner: Migration Lead

Residual Risk: Low after validation and rollback plans.
