Windows Server 2008 R2
SQL Server 2008 R2 SP1.
I have a three node 20 instance cluster, with 10 instances on two nodes, and one as passive. I want to patch only twelve instances to SP2 and leave the others at SP1 for another time. I notice that the command line patch installer only allows ALLINSTANCES or one instance. If I patch one instance at a time, I get forced to reboot. I only want to reboot at the end.
Is this possible?
