OK, I have a Win2K server with Exchange 2K installed. I have been meaning to upgrade, so now I have a chance! I am getting an inaccessible boot device blue screen from my current installation after I installed .NET and MDAC. and rebooted. It could be a laundry list of things wrong with that installation. But, what I would like to know is, if I install a new drive and install WIND2K3 with Exchange 2K3 on a new drive, can I pull over my old information stores? I have a feeling I will be able to read the drives, the OS just won't boot on them. But, I have to get my Exchange data back. Your thoughts would be greatly appreciated.
