I was thinking of just adding adding an extra drive and then moving it to the new system. The only problem is the clones will all have the same uuids. If at some later date the drives got mixed up I could see a possibilities for disaster. Not exactly likely as the computers will be in different cities. Is there a way to change the uuid if a raid array? Is it really worth worrying about? John
