Currently using SEP 11.0.4202.75 in a Windows XP environment. Planning to upgrade to 12.1. If I upgrade my management server (Windows server 2008) to 12.1, and then upgrade my GUPs (Windows server 2003), can I use the GUPs to distribute the upgrade to 12.1 to the remaining clients? I see that this feature was the topic of some discussions in 2010 but in searching the forums I couldn't find a definitive answer on whether it is possible in 12.1. Thanks for any assistance.
