I have an Exchange Server 2013 running on windows 2012 R2 as a VM on hyper V 2012. I want to configure Database Availability Group. I had installed another VM with Windows 2012 R2 and planned to install exchange on it. What is the best practice for configure DAG for exchange 2013 running on hyper-v ? Is it possible to install client access role on DAG member server (new exchange) ?
