Look, create a new home where you want it, copy over the old home, and update
your fstab.

e.g. If home is currently /home and you want to move it to /usr/home:

# mkdir /usr/home
# cd /home
# tar cf - . | (cd /usr/home; tar xf -)
# vi /etc/fstab

Edit the location of /home if there is an entry for it.
