I need to upgrade my Exchange 2010 servers configured in a DAG to SP1. Here is our setup:
ExchangeServer01 - Outlook Clients point to this server to connect
ExchangeServer02 - Holds the active mounted Database Copy
My plan is this:
Switchover the database to ExchangeServer01. Install SP1 on ExchangeServer02. Once ExchnageServer02 has SP1 installed I will switchover the database to ExchangeServer02. Now I will install SP1 on ExchangeServer01. Once ExchangeServer01 completes the SP1 install I should be all set.
Any potential issues with this plan? Any other considerations?
