Have following servers:
DC Windows 2008
Exchange 2010 mbx on Win 2008r2 Site 1
Exchange 2013 mbx on Win 2012r2 Site 1
Exchange 2013 mbx on Win2012r2 Site 2
The exchange 2010 does not have DAG setup before, we are in process of migration from Exchange 2010 to Exchange 2013. We started building DAG only between Exchange 2013 servers. I am not sure if the DAG setup is same in Mixed mode will support. We had set the service connection point to Exchange 2010. Does it affects DAG? Do we have any article saying how to build DAG in mixed mode environment during co-existence.
