Yes I have followed the same approach as you mentioned. I am stuck with the postgis extension installation as it has many dependencies for postgresql 12 to create an extension on RHEL 9.
Actually we are migrating from centOS7 to RHEL 9.

not sure whether my last response came through

so you can not just run your pg12 restore on a pg13 instance

so #3 would be the thing I'd try
- restore the backup from v12 to a temporary directory into your
server runnig v12 AND v13
- run pg_upgrade
if you don't know how that works in detail let us know
