Re-install.  You can't use dd(1) to copy a disk image to a smaller
physical drive: the disk size is encoded in various structures on disk
and used at boot time; copying a filesystem with dd(8) and  truncating
it (even if the used space is less than the target partition size) just
doesn't work.

If you have work you've done on the original disk images that you'ld
like to copy to the new ones, then use a file-system level copy program.
There are any number of suitable candidates, most of which have the
ability to write across a network link if needed:

   * dump(8) and restore(8)

   * rsync(1)

   * tar(1)

   * find(1) and cpio(1)

Even cp(1).

	Cheers,

	Matthew
