I personally tend to use:

This takes care of purging the configuration files of packages

the cluster(s) have migrated).
Thank you, I didn't know about mixing "dist-upgrade" command with "purge"!
Now the system is really in a clean state with only debian12 packages
installed.
Is it? Remember that apt doesn’t know about leftover conffiles.
Try: dpkg -l | grep -v ^ii | cut -c 1-$COLUMNS
Yes, it is :)
I run similar commands during the cleanup when we noticed the gnutls
problem. All non debian12 packages are now purged. Just to be sure that
there really isn't any leftover or manually added file which could
interfere in some unexpected ways I even feeded all files through dpkg.
