Hi Jim,

You should have no troubles reassembling the array on a new machine.
From what I understand, md raid doesn't depend on device names for
assembling arrays, it has some internal UUID's to distinguish which
array a member disk belongs to.

mdadm --assemble --scan is pretty much all you need (and won't break
anything in the process)

Is there a way to rename md devices?  It would be useful in general and
maybe necessary if assembling the arrays from the other system causes
md device name collisions
