Hi Henry
Unless you use the server as a workstation, you don't have to re-install Adagio from scratch. You can simply copy the contents of the \Softrak folder (and all subfolders) from the old server to the new one. I would recommend creating and sharing a folder called Adagio on the new server and copying the contents there.
On each workstation, re-map the Adagio drive from the old server to the new server, preserving the same drive letter if at all possible. If not possible, then you will have to re-install Adagio.
I don't work for Softrak, so this is an unofficial suggestion. But my experience is that it works and is the easiest approach.
