Total 4 Exchange 2010 Server running SP1 with RU6.
Two MBX server are setup for DAG
Two are setup as CAS/HUB
What is be procedure to upgrade , i mean which role first.
Regarding DAG I see Org Configuration --> Mailbox --->Database Management where I see all the database 4 database are mounted on server 1 and copies on the server and vice versa for the server 2.
Going forward do i need to Right click on the Database and move it to the other server one by one and the install the service pack?
And what needs to backup if it needs a backup?
