Answer 1

Hi @azhar Nasim ,

According to your description, to narrow down our issue, please clarify the following questions：

“After data movement 2 Copies of DAG are gone offline and Exchange Transport services got down on one server”

Do the 2 copies here refer to the source and target server replicas? what about the current DAG copies status, return to normal?

“I have shifted user mailboxes from One Exchange server 2016 dag member to another member”

What is the status of user mailboxes after migration?  

Besides, please have a look at the event viewer on the Exchange sever and see if there are any event logs when the issue occurs.

The virtual dir URLs on each server should all be the same, pointing to the Load Balancer pools ( or DNS round robin if using that).
