 ## Upgrade
 
+> Warning: The 5.11 release updates the database container images from Postgres 12 to Postgres 16. Customers are advised to have a database backup before upgrading! See our [postgres 12 end of life](https://sourcegraph.com/docs/admin/postgres12_end_of_life_notice#postgres-12-end-of-life) notice!
+>
+> Single-container *does not* support auto migration to postgres 16. If you are planning to upgrade to 5.11.0 and beyond on single-container, you will need to dump the postgres databases and restore them after the upgrade.
+> In this event, we highly recommend you migrate to a production supported deployment method, or switch to our cloud offering.

 ### Standard upgrades
 
 A [standard upgrade](/admin/updates/#standard-upgrades) occurs between two minor versions of Sourcegraph. If you are looking to jump forward several versions, you must perform a [multi-version upgrade](#multi-version-upgrades) instead.
