What it means
Data migration integrity verifies that transferred files, databases, metadata, permissions, ownership, timestamps, and records remain complete, accurate, authorized, and recoverable across platforms.
Why it matters
A migration can appear successful because files exist at the destination while security attributes or application-critical details have been lost or changed.
Practical focus
- Define the data, metadata, security attributes, and applications included in migration and the security outcome it must support
- Apply validated tooling, protected transport, checksums, reconciliation, backups, and controlled cutover through documented, reviewable configuration
- Verify record counts, hashes, permissions, rejected items, application behavior, and rollback readiness after changes and on a scheduled basis
- Plan for silent truncation, encoding change, permission loss, or incomplete cutover, including rollback, ownership, and escalation
Common mistakes
- Enabling a feature without defining what it should protect
- Relying on defaults or one-time validation
- Granting broad exceptions that erase the control boundary
- Treating silent truncation, encoding change, permission loss, or incomplete cutover as an operational surprise instead of a test case
