I am currently running SBS2003 and I have had my discs for a while now for SBS2008. I know that you can't just upgrade the server because it goes from 32bit to 64bit. I also know my server is capable of 64bit OS.
Here is what I would like to do. I would like to upgrade my server by first installing a VMWare layer, then installing SBS2008 as a virtual machine. I will probably add another virtual machine at a later time. But I would like to keep my data from my SBS2003 installation and transfer it over. The actual data isn't a problem, because that is simply moving it to a NAS then back. But what about Exchange data and domain data? Is there a way to migrate Exchange and Active Directory Data over to the new installation? Keeping in mind since I will be using the same server I can't use the SBS2008 migration that puts it on a new machine.
