Primary Site is on SP1, numerous Secondary Sites still on RTM, some SS's are on SP1.
I just noticed the PS has SP1 CU2 installed. None of the SP1 SS's are on CU2 - only the PS.
Is this a big deal? I know that you're not supposed to roll out CU2 to your servers until SP1 is installed on all Site Servers, so this worries me a bit.
