I am preparing for a migration from Exchange 2007 running on Windows Server 2008 to Exchange 2010 running on Windows Server 2008 R2 and one of the things we are going to do is implement Database Availability Groups (DAG) instead of CCR.
In preperation for this we will need to figure out how to properly destroy/remove our CCR cluster without causing any damage to the overall arcitecture. We would like to remove the CCR portion and rebuild one of the current CCR machines as a 2010 Database Server. In order to sucessfully complete this we will need the other member of the CCR cluster to remain functional while we move mailboxes.
Has anyone done this yet? Does anyone have any suggestions on the best way to accomplish this?
I found the following Technet Artcle but I am wondering if anyone has any other articles/suggestions before we proceed: http://technet.microsoft.com/en-us/library/bb885058(EXCHG.80).aspx
Not sure on the exact steps&
1. Use the Exchange Server 2007 SP1 Setup Wizard to remove the passive clustered mailbox role from a node in a CCR environment (http://technet.microsoft.com/en-us/library/bb124756(EXCHG.80).aspx
2. Then what? It would seem that I would still have a CCR cluster that is utalizing the File Share Witness to operate. How do you remove the cluster completely but maintain a functional enviroment?
Thank you for any help you can give,
