Database schema migration safety analysis evaluates lock risk, backward compatibility, and rollback viability. Pointing the analyzer at migration files detects risky operations like lock-heavy changes and provides non-destructive remediation guidance.

Adding NOT NULL columns without defaults risks blocking writes and breaking backward compatibility. Migration analysis detects this pattern alongside risky column changes, generating guidance on data preservation and safe deployment strategies.

Yes, migration analysis can scope to files changed since the last commit. This targets risk assessment during active development and deployment planning, reviewing only modified migration files rather than the entire directory.

Planning a rollback strategy requires evaluating rollback viability of migration files. The analysis generates guidance on rollback pathways and data preservation techniques, ensuring safe migration reversals if deployment issues occur.

No, migration analysis is strictly read-only. It evaluates schema migration files without modifying your database, providing non-destructive recommendations and actionable remediation guidance for safe deployment planning.

Validating backward compatibility requires automated migration analysis checking for lock-heavy operations, NOT NULL constraints without defaults, and risky column changes. This read-only evaluation provides remediation guidance before deployment.
