Move software raid to new machine

[Johannes Wiedersich <johannes@physik.blm.tu-muenchen.de>]

Dear all,

I would like to move our software raid array (mdadm) to a new hardware.
Currently, I have one disk for the system etc. and two 'identical disks' 
that serve as software raid 1.

Can I just move the two discs to the new machine? Do I have to take care 
that they retain their names as /dev/hdb and /dev/hdd? Is there a way to 
rename them to say /dev/hda and /dev/hdb?

Note: the new machine has one sata disk, so /dev/hda will become known 
as /dev/sda.

Thanks,

Johannes
