Which version of pg_basebackup are you using to take backup of 11 version?

See here:

https://www.postgresql.org/docs/13/app-pgbasebackup.html
"pg_basebackup works with servers of the same or an older major version,
down to 9.1."

What is the exact command you are using?

You will still need to VACUUM, though AUTOVACUUM should take care of that.

Not sure what you mean about upgrade?

The new features will be available to you.
