Prechecks

Confirm the current release and namespaces:
Back up mutable admin resources:
Save current Helm values:
Prefer a maintained values file over --reuse-values. This avoids carrying old image tag overrides forward accidentally.

Manual Helm upgrade

If you must use --reuse-values, set image tags explicitly:

Post-upgrade validation

Port-forward and check health:
Open the Admin UI and verify login, deployment list, diagnostics, logs, and metrics.

Rollback

List revisions:
Rollback to a previous revision:
After rollback, rerun the post-upgrade validation commands.
