Exchange DAG Mode - Network Disruption?

DaveQuance asked
I'm going to be implementing a DR site in my environment. I currently have two dedicated MBX servers in a functioning DAG. I want to switch the mode of that DAG to DAC. I need to know if I can do this during normal hours or if I have to wait for a maintenance window. My web searches weren't of any help.

Will changing an Exchange DAG mode to DAC cause disruption to email at all?

Hiya it wont effect anything as DAC mode just dictates what happens in a failover. You can enable DAC without it effecting your current DAG or your mail users.


Thank you for the quick response, your reasoning makes perfect sense.
