I have a DAG of six servers. Here is the detail:
2 servers with Cas and Hub
1 Server with Cas, Hub, and Mailbox databases
3 Servers with mailbox databases
All servers are running Exchange 2010 SP3 and Windows Server 2008 R2
I am also running SCCM 2012 as well. I patch my other servers and clients with SCCM 2012 but now I want to patch my Exchange 2010 servers as well in automatic way (if it is possible). If auto is not possible what is the best practice to patch them. I did Google but couldn't find any latest article on it. So here is my requirements:
1. What is the step by step procedure?
2. What's the sequence of actions?
3. Will be there any downtime even disconnection?
