I need some bulleted steps on the process to undo a DAG on a production site/setup.
I have two notes, same subnet in two separate states.

two exhange server
1 dag
dynamically assigned ip
primary node Exch1 one is
secondary node Exch2 two is
WFS is on a separate server in the 192.168.100.x nw
Both servers are Hub, Client, Mailbx servers.

I need the primary node Exch1 to be the one remaining exchange server, no DAG, no cluster in the windows failover cluster manger and at the end of the day no errors with my one remain exchange server.

First of all make sure you have a health copies of al DBs on exch01.

Run :
C:\>Remove-DatabaseAvailabilityGroupServer -Identity DAG -MailboxServer Exch2 -ConfigurationOnly

uninstall mailbox server role from exch2...

C:\>Remove-DatabaseAvailabilityGroupServer -Identity DAG -MailboxServer exch1 -ConfigurationOnly

delete the DAG from EMC.

Will review this and comment again shortly today, but does the process require any services to be stopped when dismanteling the DAG?  If so when and which and steps?  Anyone actually done this and have any expierences insights to share?  Also, how long is this process overall can I anticipate?  Anything that can happne, should be watched out fore, etc...?

I dont think you need to stop the services ..... I have got DAG and i have never on EE heard a removal of DAG so not sure to be very true .... might catch up with Internet to see if anyone has done or tried and what they found or did :)

Prefer to take System state and Exchange DB backups :)
