I am in the process of migrating from Exchange 2007 to Exchange 2013. I have two Exchange 2013 servers in a DAG. I need to create the customised receive connectors that exist on the Exchange 2007 server on the Exchange 2013 servers. When I create new receive connectors for our DAG members, do I specify the IP address of both servers in the network adapter bindings field, do I specify the load balancing IP address, or do I need to create an instance of the receive connector on each server, and bind the connector to the IP address of each respective server? Similarly, what do I need to specify for the fully qualified domain name (FQDN) the connector will provide in response to HELO or EHLO?
Also, I have multi-function copier/scanner/printers that users use for scan to e-mail purposes. On these devices, I need to specify the SMTP server by FQDN or IP address. What do I specify when I have two Exchange servers in a DAG, and either one of them may be the active server because the other is unavailable due to system maintenance or an unplanned outage?
