I ran out of space on a DAS device and need to migrate the data to much larger iSCSI based drive on the same server. There are multiple shares and levels of permissions. I'd like to retain both permissions and shares and ideally swap the drive letters so that if hidden shares are mapped they will stay that way.
What's the best process? Do I use robocopy, xcopy? DFS won't work because this is all on the same machine.
