-      You're currently deploying an older version of Hydra which is needed to
-      make some required database changes[1]. As soon as this is done, it's recommended
-      to run `hydra-backfill-ids` and set `services.hydra.package` to `pkgs.hydra-unstable`

-            The Hydra package doesn't exist anymore in `nixpkgs`! It probably exists
-            due to an overlay. To upgrade Hydra, you need to take two steps as some
-            bigger changes in the database schema were implemented recently[1]. You first
-            need to deploy `pkgs.hydra-migration`, run `hydra-backfill-ids` on the server
-            and then deploy `pkgs.hydra-unstable`.
-
-            If you want to use `pkgs.hydra` from your overlay, please set `services.hydra.package`
-            explicitly to `pkgs.hydra` and make sure you know what you're doing.
