Run the target version upgrade hook to move the SQLite database and its SQLite sidecars from the previously published serverkit-data volume into the new app-local bind directory. Keep the migration scoped to installs whose old Compose still used the named volume and retain the legacy volume for rollback.
Store the SQLite data directory under the 1Panel application install path so application backups include it. Initialize the bind directory with the image runtime UID/GID and keep both packaged versions upgrade-safe.
