I'm upgrading from Acad2004 to Acad2005. From reading this list I understand that I can upgrade flexLM to version 9.2 (for Acad2005) by stopping the service and uninstalling the old version and installing the new version. Or I can just copy the 4 key files from the CD. Then I can use my existing .lic file as is. Even though my serial number is different. The end result will be that I can serve my 18 licenses to either Acad2005 clients OR Acad2004 clients. Do I understand this correctly? What about the need to install a new Network Installation Wizard. I don't build my network install images from that server, do I still need to upgrade it? (If it even exists on that machine) thanks, mjm
