We are on April 2022 CU for Exchange Server 2019. In the middle of the upgrade from 2016.
When we configured DAG on 2019, both the MAPI and DAG network got associated with the same DAGnetwork. When we try to modify it gives the below error.
If we try to remove it says active subnets present.
If we run the below commands we get the error listed below
Set-DatabaseAvailabilityGroupNetwork -IgnoreNetwork:$true
Set-DatabaseAvailabilityGroupNetwork -ReplicationEnabled:$false
WARNING: Replication is disabled on all networks. This is not a recommended configuration. Replication will still be attempted via DNS resolution of mailbox servers.

JoshGardner , is this the same issue you are facing as well?
The_Exchange_Team Bhalchandra_Atre-MSFT , these are new DAG that we created today. Would Deleting and re-creating the DAGs would help
Or any other things we could try out?
