You can either do an in-place upgrade and then move from one server to the other or vice-versa. It doesn't matter. To move 200GB I usually hand it over to the server admins to restore from back up or something. If you really (really) have to do it then TeraCopy is something that I would recommend. It's free! There are a few others that you can buy and do a good job of copying huge data.HTH
