You would be safest if, for the disks/partitions you are transferring, you made the partition type 0x83 (linux) instead of 0xfd to prevent the kernel autodetecting. Otherwise there is a risk that /dev/md0 and /dev/md1 will be transposed. Having done that you can manually assemble the array and then configure mdadm.conf to associate the UUID with the correct md device. David
