# Enterprise operations

> Upgrade, rollback, backup, restore, and support

Before an upgrade, run the package preflight, take a portable PostgreSQL dump,
verify Cloud SQL PITR and object versioning, render and archive manifests, and
review all permission, network, Secret, node placement, and image changes.

Use Helm `--atomic --wait`. If readiness fails without a schema change, Helm
returns to the prior revision. Migrations are forward-only and idempotent. A
rollback across a schema change restores the pre-upgrade dump into a new
database and deploys the previous image digest; never restore over the failed
database.

Quarterly restore drills verify migration ledger, record counts, audit export,
receipt reads, recovery point, and recovery time.

The support-bundle script collects bounded workload state, warning events, Helm
history, and logs. It does not query Kubernetes Secrets, Helm values, source
artifacts, diffs, evidence objects, or database rows. Operators must inspect it
for unexpected customer data before sharing.
