Great catch. I booted the machine with the Acronis DVD and it does see the virtual drive and its partitions with the correct formats but there is no indication that it knows it is a "raid volume".
I recently used this same process to upgrade the raid drives on a Dell PE T-100 server with a Dell SAS 6/iR raid adaptor and it worked wonderfully.
I guess can give it a try to see if works. If it doesn't work however, is there anything special I will need to do to when I put the old raid drives back in?
Thanks for your help.
