Yes. The dump/restore should do the trick as long as you have another medium
to store the dumps (such as another hard disk). You will store the images of
your slices to the new medium using dump(8). You can then use FixIt console to
re-partition and re-slice your hard disk and then restore(8) your images in
the newly sliced hard disk. Actually, if you have another hard disk device,
you can use piped dump/restore to copy the whole system from one disk to the
other and make the second one your bootable disk. Of course you must have
sliced the second device first.
I've done this many times. The first was to remove an openSUSE partition I had,
living in the same hard disk as my FreeBSD. The second time was to move my
FreeBSD to another hard disk (physical device). The new disk became my boot
The third time was to move my system to another bigger hard disk device and at
the same time be formated as ZFS.
Now my system boots from this third hard disk device, having ZFS and the
operating system is the same as that I first installed (of cource updated...)
