You're going to need a HUB Role in there too, you can run the CAS and HUB roles on the same box.
You still need Windows Clustering Services for a CCR cluster. Here's some highlevel reading: http://technet.microsoft.com/en-us/library/bb124521.aspx From: Jason Tierney [mailto:[EMAIL PROTECTED] Sent: Monday, June 16, 2008 11:32 AM To: MS-Exchange Admin Issues Subject: Exchange 2007 Cluster I have a customer interested in migrating their Windows 2003/Exchange 2003 FE/BE environment into a W2K8/E2K7 Cluster (for the mailboxes only). As this is not my usual area of expertise, I would appreciate any advice you have to offer. My thoughts are that we need two new servers to make up the CCR cluster and the E2K7 MBOX servers. From what I can tell, CCR is not a Windows cluster, but an Exchange thing, so I don't need to worry about quorums and the like. The existing FE would be upgraded to an E2K7 CAS. I guess my question is, what happens to the other roles? There are only 500 users or so and things run really well on two servers now. They aren't really interested in an Edge server, but obviously the Hub Transport role (and maybe an internal CAS) needs to go somewhere. They can run on the CCR, right? Thanks for your help!
