The new ZFS is backwards compatible with the old one. So your 12.2-p3 system will be able to zfs send, and the stable/13 will be able to zfs recv. You can go the other direction too, if you're careful to create the new pool using the old format, and don't turn on any of the new features. /etc/rc.conf shouldn't need any changes. Your upgrade plan sounds fine. But for the "backup all data" step, I would recommend using zfs send/recv to do the backup. That will do a better job of ensuring your files' integrity than something like rsync or cp.
