I'd say copy everything in /var to /mnt.
cp -a /var/* /mnt
cp -dpR /var/* /mnt
That way you don't lose anything if there's a power cut at an inconvenient time, and you can change ftstab, reboot, and then check everything's working before you hose your original /var (which if you do it this way you really only need to do if (a) "/" is full and (b) original /var is big enough to be worth the trouble reclaiming the space (but remember to go into rescue mode and unmount your new /var first, if you do this!)
