 - **Admins using external dbs who have not yet upgraded from postgres 12 to postgres 16**, can expect to see database drift after upgrading to `5.10.0`. The new expected schema definition for Sourcegraph is based on postgres 16. The schema drift is the result of automatic changes made to the schema by pg_upgrade utils, and will not cause issues in the application.
   - Admins should not run migrators suggested drift fixes, and should instead upgrade their database from postgres 12 to postgres 16.
 - The [Autoupgrade](https://sourcegraph.com/docs/admin/updates/automatic#pre-v500-automatic-multiversion-upgrades) upgrade method, will detect drift and exit before conducting the upgrade unless the env var `SRC_AUTOUPGRADE_IGNORE_DRIFT=true` is set in the server container.
