What is the rationale for choosing 12.5?  The current v12-branch release
is 12.11 (and 12.12 will be out next week).  So you're missing nearly
two years' worth of bug fixes.  A quick look through the release notes
shows at least one pg_upgrade fix that could be relevant, from 12.8:

      Make <application>pg_upgrade</application> carry forward the old
      installation's <literal>oldestXID</literal> value (Bertrand Drouvot)
