I am currently on SP2 RU5 V2. I had been looking into installing SP3, but am questioning if this is a smart move in my environment. We moved to Exchange 2010 about a year ago from 2003, and do not plan to move to 2013 in the near future.
From what I see, SP2 Ru6 includes all the same updates as SP3, with the exception of compatibility with Exchange 2013. Is that pretty much the case?
I have been reading some issues in general with RU6 and SP3, such as the inability to soft delete emails in some cases. Uninstalling a RU is not a big deal, but it looks like SP3 is an all in proposition, and there is no going back once you start without recovering servers.
I realize that in about a year, updates for SP2 will no longer be released, but at that point I would imagine a much more mature SP3 will be out there.
So is there any compelling reason at this time for me to go to SP3 and take on all the additional risk, or does it make more sense to just go with SP2 RU6 in this case.
In fact, with some of the issues with SP2 RU6, and no compelling security reason to update, I am thinking of skipping it all together and waiting for SP2 RU7 or SP3 RU1.
Any thoughts / experiences on this?
