I have been delegated the task of patching Exchange 2010 SP2 exchange servers. I am kind of new to DAGS but not patching windows 2008 R2 servers. I have read many things including Microsoft having a script for SP1 and RTM to fail over the databases to another server. if someone can help me I would appreciate this. Anyone who has ever patched DAGS can you provide me a high and low level list of things to look for. Our environment is 3 exchange servers and all the roles are installed on each HUB-CAS-MAILBOX server having the dags with 5 databases on each.
One of the major first things is to failover the active mailbox copies to another server. I know I can do this through the command shell move-availabilityserver I think or through he GUI do a manual switchover to another server. Can someone provide more info it will be really appreciated, thanks
