Well, that should be easy.    You just have a new disk, slice, partition
and newfs it with a new UFS2 system.  Then dump the old partitions
and restore them on the new partitions.    It is still a matter of
creating a new system with new space.  You could do it to a spare
machine and then once it is all built, do the same back to the old
machine and it would all be up-to-date.

The new one would be nice and clean then too.
