Question: Should I download and install UR#3 for OM12?
Cameron Fuller posted some time ago a good article about the same question for UR#2. Basically he said: ‘If it ain't broke, don’t fix it’. And I concur with him on that one. Same goes for UR3# for OM12. Only install it when you experience one or more of this issues mentioned above. For all other situations you better wait until SP1 for System Center 2012 goes RTM.
