Hi,
We are planning to patch 3-Node Active-Active-Passive Cluster running SQL 2008 R2 from SP2 to SP3. The cluster configuration has 2-Clustered Instances. I want to know what is the best practice to patch these servers. Can I go ahead with patching 2-instances on Passive Node at once or do I need to patch for each instance separately for each node?
Welcome any suggestions from you guys.
Thanks ,
Sanjeev
