Hello,

I have two Exchange 2013 SP1 servers with DAG configured. I want to upgrade them with CU8. Kindly advise how to do or is there any step by step document available for upgrading the DAG member server.

Thanks in advance.

yes you need to upgrade one at a time and putting them in maintenance mode

this article has step by step info

Thanks for reply. How can we put the server in maintenance mode, what is the procedure?

and what happened if we manually move all the Dbs to passive node and upgrade the active node directly without keeping it in maintenance mode?

did you even read that article?

Yes I read the Aticle. but my question is; If we manually move the databases on second server and run the CU8 setup directly on first node without keeping it in maintenance mode, what will be the impact?

it will impact on transport services

ok understood.

Thanks
