How to upgrade old MW Postgres DB backup into much newer MW version?

We had Mediawiki with PostgreSQL on a Debian 8 server. That machine is
no longer accessible, but there is a backup of the database.
The old versions were:
- Postgres v. 9.4
- Mediawiki v. 1.25 or 1.27 ?
Now we installed Mediawiki and PostgreSQL on a new Debian 11 server. But
the database schema seems to be quite different so it will not be
possible to import the backup directly.
Our current versions on Debian 11 are from the "stable" ("bullseye") apt
repository:
- Mediawiki v. 1.35.8
- Postgresql v. 13.9
Is there a collection of database upgrade scripts somewhere, which I
could use to upgrade, step by step, our backup DB to the current schema?
(The import of the SQL backup into Postgres v. 13 works fine. But then
the schema needs to be adapted to what MW expects)
Thank you for any help,
MI
