I have Windows 2008 R2 on a PE R720XD with 5 TB of usable space on internal disks and an MD1220 with almost 12TB attached in unified mode. About 8 TB are in use between both sets of disks, all on one Windows volume.

I'm starting to plan for a move to a new server, probably an R540 or R740. Assuming I have enough free space on the MD when the time comes (or I may have a second one daisy chained by that time), is it possible to make all the data move to it so that I can shut down the old server and then just connect the MD to the new server?

Adding: The data are all backed up to a dedup device, so restoring from that is an option, but I'm hoping that I can avoid having to do that.

Thanks.
