A handy thing to do is dd over netcat.  Boot both machines using knoppix
or something and get them networked.  Then you don't have to take
the machines apart.  e.g.

on recieving host
  netcat -l -p 12345 | dd of=/dev/hda
on sending host
  dd if=/dev/hda | netcat 'host' 12345 

When the physical disks aren't identical, or you just want to go faster,
you can use ssh, sfdisk, mkswap, mke2fs (and friends), tar, etc. to do
this kind of thing.  I've written some (rather sloppy) scripts to do
this kind of thing if you're interested.
