Updating and Rollback

Updating and Rollback

Back up Prizen before every update. Use the same explicit version for the application image, Compose application, and GitHub Release asset.

For Docker, replace the version in the OCI Compose reference and run up -d --wait. For Podman, download the new release asset and set PRIZEN_IMAGE to the matching version.

The migration service runs before the app and tracker start. Never mix a Compose file from one release with an image from another.

Rollback may require restoring the database and secrets backup taken before the update. Changing only the image tag is unsafe after an incompatible migration.
