remove manually added exchange server 2019

Question

I have upgraded my exchange server and installed new server build both are same version and build now.

my case is now I'm working on standalone server and I need to build the DAG .

I tried to add from exchange ECP the non-production server and it was added , however I need to add the second production server to DAG it is showing old DAG name which I can't see it in the ECP

I got this error : removed from the cluster before it can be added to database availability group.

Hi @abdulqader naji ,

Please try the following steps:

1.Remove the production server from the old DAG.

Remove-DatabaseAvailabilityGroupServer -Identity OldDAG -MailboxServer <the second production server>

2.Import the Failover Cluster module into Exchange Management Shell session.

Import-Module FailoverClusters

3.Remove a failed node from a Windows Failover Cluster.

Get-ClusterNode <the second production server>| Remove-ClusterNode -Force
