Pre-Upgrade Checks

Check Current Version

Confirm the currently running package version, image tag, database migration version, and Console UI version. Record the current entry domain name, deployed nodes, and upstream model services.

Check Service Status

Confirm that gateway services, PostgreSQL, entry proxy, and upstream model services are healthy before upgrade. Do not start an upgrade while the existing environment is already abnormal.

Check Change Content

Read the release notes and identify whether the target version includes database migration, Route Policy changes, credential changes, Console UI changes, or LobsterPool-compatible entry changes.
