We are currently running Pro/E WF 3.0 and are planning to switch over to WF 4.0 sometime next week. Our FlexLM license server is on version 10.8 on a Win2000 server machine. Do I need to install a new (i.e. updated) version of the FlexLM license server or can I just swap out my WF3 license file for the new WF4 license file? Still keep version 10.8 of FlexLM?
