I did already once the following:

1. installed sysutils/clone from the ports
   # pkg install clone

2. dd'd the latest snapshot onto a USB memstick
   and mounted /dev/da0s2a to /mnt

3. (optional) saved the changed settings in /etc and /boot

4. used several clone commands in synch mode for replacing
   the old snapshot installation by the new one using the
   following shell script

#!/bin/sh

clone -s -x local /mnt/usr /usr
clone -s /mnt/sbin /sbin
clone -s /mnt/rescue /rescue
clone -s /mnt/libexec /libexec
clone -s /mnt/lib /lib
clone -s /mnt/bin /bin
clone -s -x loader.conf /mnt/boot /boot
clone -s -x fstab:group:localtime:master.passwd:motd:passwd:pwd.db:rc.conf:rc.local:resolv.conf:spwd.db:ssh:ssl /mnt /etc

The above script operates on the live system, and replacing the old installation by the new snapshot takes less then 10 min.

You would need to check the exclude lists (-x) whether all your changed settings are listed.

/dev, /home, /media, /mnt, /proc, /root, /tmp, /usr/local, /var are left untouched.

If you feel more comfortable then first clone your boot device and do a test upgrade on the clone.

If you do a major upgrade (e.g. 11-CURRENT to 12-CURRENT) then you need to rebuild the ports, of course.
