# Upgrade and rollback runbook
|
|
|
|
1. Record the running image digest and take a tested metadata backup plus repository
|
|
recovery evidence before changing the image.
|
|
2. Pull/build the pinned image, then run `docker compose run --rm migrate upgrade`.
|
|
Do not start web, scheduler, or worker against an unverified schema.
|
|
3. Start the stack, wait for `/readyz`, and inspect `/metrics` for stale leases,
|
|
schedule lag, unavailable repositories, and corrupt backups.
|
|
4. If migration fails, stop and restore the prior metadata backup and matching image;
|
|
do not attempt to downgrade an unknown partially migrated database in place.
|
|
5. Preserve migration logs and verify a representative backup restore before closing
|
|
the change.
