There is a ton of how to do this on FreeBSD.
Read the man pages on zpool and zfs... read the Wikis... read the
HowTos.....
Never assume that the data will be there.... BACK IT UP! :-)
You may try:
cd /home
tar cpf . - | xz > /usr/home.tar.xz
see if it fits... if you have a 32 GB USB... real easy... put it on the
USB key...
After it's backed up, you'll need to modify the /etc/fstab to comment
that partition out.
Create a zpool with:
zpool create name (might use home) /dev/ada0s1f
It will create an internal mount point and it will automatically mount it.
If you were to use 'home' as the pool name, it will attempt to mount it
on /home .
You're changing the format of the storage from UFS to ZFS.... not the
same...
Anyhow, zfs is enabled on zpool once you start. Restore the data to the
new partition.
You should be fine.
P.
PS - I may have missed something and someone will point it out. Please,
please, please read all of the above. ZFS is amazing.... I want to have
its baby.
