We are schedule to upgrade our Window server OS and Exchange to Service Pack2. Our current enviroment of our Exhange system is active/passive (3 active node & 1 Passive node) in a cluster environment. Whereby none of our Windows boxes have any service pack on them, but Exchange has SP1. We propose to upgrade both to SP2, I am aware of the process invovled in upgrading, but is there general checklist out there, we can use to prove that the upgrade to Exchange SP2 was successful?
Obviously this will be tested on our Test network first before rolling it out on our Live environment.
