+## Upgrading this add-on from v1 to v2
+
+TeslaMate v2 introduced a hard requirement on the version of PostgreSQL database.
+**You will need to use PostgreSQL 16.7 or 17.3 or later.**
+If you are currently using an earlier version of PostgreSQL, you will need to backup your TeslaMate data, upgrade the database, and then restore the data.
+You can find details on how to do this in the "_Migrate TeslaMate to a Different Postres Server_" section of this add-on's documentation tab or in the [DOCS.md][docs-md] file in the add-on repository.
+
 ## Migrating to this version of the add-on
 
 Migrating to this version of the add-on should not result in any loss of data, but you can never be too careful, so I recommend you take a full backup of your Home Assistant instance and also a direct backup of the TeslaMate database as detailed in the [TeslaMate documentation][teslamate-backup] before proceeding.
