Preparing for ZfD3 Upgrade

I am preparing to upgrade an existing ZEN 2 installation to ZENworks for Desktops 3.

I have inherited the current installation from someone else and it has not been documented. We have 3 sites on the WAN with NetWare 5.1 servers at each site. I know that various components of ZEN reside on different servers. Is there anyway of checking which components (inventory etc) are on which server?
