(this relates to Exchange 2010, but could not find the forum for that version)
We are currently on Exchange 2010 SP2 and UAG 2010 SP1. I want to upgrade Exchange to SP3, and later on UAG to SP4, but not all at the same time due to scheduling. Ideally we'd like to do Exchange first, then a week later update UAG. Will Exchange 2010 SP3 be supported (function) on UAG SP1? Should we update UAG to SP4 first, then later update Exchange 2010 to SP3 later?
