There is the ever popular dump and restore method also.  This allows 
you to modify the slice and partition sizes.
Do something like this.
drop in new disk
format up with the sysinstall tools
mount the new partitions somewhere
restore the data to them
edit files like fstab to change the disk names in there or just swap 
the drives around in the box so the new one is logically where the 
old one was.
reboot

look at man dump and man restore
If you really want to do it this way I can supply a better dummy 
sheet.
