Exchange 2010 and Exchange 2013 Database Availability Groups

Hi,

We are planning to install Exchange 2013 on our business environment. Currently we have a Exchange 2010 DAG running on two different locations.

My question is can we add the new Exchange 2013 to the existing 2010 DAG?

Thank you.

Actually you can't add exchange 2013 server to an existing Exchange 2010 DAG because each member of the DAG must be the same exchange server version.

My understanding is that you will have to build a new DAG in Exchange 2013 and migrate the mailboxes from 2010 mailbox servers to 2013.
Once all mailboxes are moved decommission Exchange 2010 servers as normal.
