I've used Clonezilla many times, but not on a RAID system.

My question is: if it's a hardware RAID, does it matter?  Doesn't the 
hardware hide the details, making it look like a single drive?

On the other hand, RAID 1 is just mirroring, correct?  Couldn't you, in 
theory, take one drive out of the old system, replacing it with a new blank 
drive, rebuild the RAID, and the original system is back where it was, and 
then take the removed drive to the new computer, and use it to "rebuild" the 
RAID, ending up with a clone on the new box?
