Design rollback before rollout

Write a recovery decision tree before deployment, distinguishing reversible configuration changes from data migrations that need compensation.

Recovery worksheet

Record the current version, proposed version, compatibility requirements, health checks and stop conditions. Identify the exact artifact or configuration that would be restored and confirm it remains available through the project's authorized retention policy.

Data boundary

Ask whether the old application can read data written by the new one. A reversible container switch does not make a destructive schema migration reversible. Where rollback cannot restore state, define a compensating action or a forward repair and make the limitation explicit before deployment.

Example

A release adds an optional column while retaining the old field. Test old and new readers against the expanded schema before switching traffic. Deleting the old field belongs to a later, separately verified step, not the initial rollout.

Acceptance and limits

In isolation, trigger the chosen stop condition and run the recovery procedure. Confirm both service health and a representative data read afterward. Do not create backups or copy production data unless the operator's policy authorizes it. This is an original release checklist, not proof that a specific deployment can be rolled back without data loss.

Escopo e base

Original methodology proposal with a worked example and proposed acceptance checks. No external empirical result or universal effectiveness claim. Earlier unrelated citations have been removed.
