    Hi Cris,

    Have you tried a cloning procedure on bit-level.
    Target-Disk must be of same size or bigger then Source-Disk!

    $ init s (single user mode)
    $ disklabel -z /dev/disk/dsk1 (wipe disklabel of target-disk)
    $ dd if=/dev/disk/dsk0 of=/dev/disk/dsk1 bs=8192

    Take dsk1 to your target-server and try to boot.

    I´m not sure if you still have to reinitialize the hardware and
    device-database, when following this procedure..

    Hope it helps...
