(1) Back up /opt/local/etc, or the critical directories therein (postfix)
before upgrading ports.  (If you're really paranoid, also the queues
under /opt/local/var.)

(2) Keep the deactivated old version around (that is, don't use -u).

If something goes pear-shaped, you can recover by reactivating the old
version and if necessary restoring the backed-up configuration directory.
