Exchange 2007 - going from clustered to non-clustered

Clustering (2 nodes) has caused me more problems than it's fixed in the last months.  So now I want to rip it out - just go with a single Exchange server.  Can someone give some advice on the best way to move to single server after having been clustered?  We're in a multi blade Cisco UCS VMWare environment.  So at the OS/machine level there is redundancy and capacity out the yin yang.  I know we have some considerations such as the Offline Address Book which will need to be approached differently in non-clustered mode.  Thoughts, experiences, reference URLs all appreciated.

Hi Anigan,

It can be as easy as installing a new mailbox server and moving all the mailboxes to that server or as complicated as you want to make it :). Depends on your exchange version and what clustering you have in place...

THe OAB generation and public folders stay much the same, they can be on any server that has capacity for it. In a clustered environment you would see people generate the OAB on the active node (which causes loads of fun as it does not fail over with the rest of the server!).

Feel free to ask any questions you would like and I'll answer to the best of my abilities

**EDIT** nvm the version, too early in the morning for me and I missed you are running exchange 2007. What clustering are you using? CCR?

Firstly what Cluster is being worked upon SCC or CCR ?
It would be as simple as evicting the Passive node from the Cluster then removing Exchange completely from it and installing a fresh Exchange with another Name and IP and get it going as a new Mailbox server and then move all Mailboxes and other roles such as OAB and others.
Once all is moved to the New Mailbox server destroy the Active Node with Exchange and Windows cluster and bring it back as a Standalone Mailbox server as well to have 2 Mailbox server that can equal the number of mailboxes and then give you a kind of redundancy.

If you have any further Queries do let me know.

Thank you guys.  I had to move to going non-clustered and rely on my VMWare failover mechanisms because the Exchange cluster fail-overs were causing too much havoc with my users.  Would have like to have run this fully to ground but too much going on.  Appreciate your insight!
