I recently replaced a dying Hard Disk with a newer and bigger one. To
move the data to the new disk I used dump/restore, and stored the data
on my server.
1. dumped all slices from the machine to the server
2. replaced the disks
3. did a basic FreeBSD install from CD ROM to get a proper disk layout
and a boot manager. Because of this installation I got the same slices
as on the old disk, just with a new size matching the new disks
specification. So the slice names remained the same.
4. restored the previously dumped slices to the new disk

BTW: As long as you don't remove/destroy the data on the original disk
there's nothing desastrous that can be happen to you. If the method
you choose doesn't work somehow, you can still create another backup
of the original disk.
