We are planning to upgrade Exchange 2010 to SP3 with latest rollup updates. We have 3 HUB/CAS servers and 3 mailbox servers in a DAG. We are not quite confident if we can install Rollup updates right after applying SP3 to all servers. We think we probably wait a few days after applying SP3 to identify any potential issues before move on to the rollup updates . However SP3 is quite buggy and it requires patching as soon as possible. What's your best practices and experience? Thanks in advance !
