I have a VM that is acting as a file server currently running server 2003. This server holds about 7 TB worth of files over several data disks. As part of our windows server 2003 retirement plan I need to get these files onto a 2008 or 2012 server.
In the past I have used robocopy to do do a copy and then delta copy right before cutting the server over. Due to the size of this data I was thinking rather than using robocopy to move the data I would build a new 2008 r2 server and then remove the data disks within vmware and simpy attach them to the new server. At this point I would only need to set the drive letters correctly and everything should be there for data, permissions, etc. I would need to recreate the shares but that would be simple enough.
Has anyone done this migration method in the past and did it work for you? Anything I should be worried about with detaching and reattaching these data drives.
