In addition to what Peter said, always ensure that you read the release notes for updates and service packs. The deployment order is clearly listed in the release notes for SP2.

I want to apply SP2. I have the procedure for the Cluster but I was wondering if should I apply the service pack to CAS/HUBS first, or after I apply it the Mailbox CCR cluster? Has anyone upgraded to SP2 yet? Any issues?
