I’m upgrading our PassagePoint workstation to Window 7 from XP and I need to transfer the License how can I accomplish this? Also we have several different PassagePoint workstations how do I know what PC is using what license?

PassagePoint licenses sit on the server.

If this is a client machine, you don't need to do anything in terms of licenses. The new machine will connect and use the existing license on the server.

PassagePoint's license is concurrent usage. For example, you could install 1000 clients, but if you have 5 licenses only 5 can log in at any given time.  The server software itself running does not take up a client license.

A license is only taken up when a user logs in.
