moving FreeBSD 5.3 to a new drive

[dave]

Hello,
    I've got a 5.3 box that has outgrown the drive it is on. I really do not
want to back it up and do a reinstall unless i have to. I'd like to move it
to a new, larger disk, plug in the new disk, and boot it. I know i can use
dump/restore, but i don't know how to make bootable and any differences in
files first vs. second disk.
Does anyone have a procedure for this?
Thanks.
Dave.
