I need to upgrade a 5.3 Meetingplace to 6 and will need to go from Win2000 to Win2003. The upgrade kit came with platform discs that show that they are for 7835-H2 while we have 7835-H1. Are all the OS2003 discs the same or are they individualized for the application. In other words, can I use a UCCX disc for the meetingplace server?
