How do you know this worked?

To verify that you've successfully removed the DAG, do one of the following:

  • In the EAC, go to Servers > Database Availability Groups, and see if the DAG is still displayed.

  • In the Exchange Management Shell, run the following command to see if the DAG still exists:

    Get-DatabaseAvailabilityGroup <DAGName>

    If the DAG was successfully deleted, the preceding command will produce an error message indicating the object could not be found.
