Converting to a CAS Array - Exchange 2010
Hello Experts!
I'm in the process of creating a redundant Exchange environment. I currently have a single Exchange 2010 server with MBX, CAS, and HUB roles, which handles everything in my single site production environment.
My question is about implementing a CAS Array. I have four new servers configured, 2 CAS and 2 MBX. I'd like to convert the CAS servers to an array, but read that it will add all CAS servers at my site into the array. I'm pretty sure, this would have serious repercussions for our clients connecting to the single CAS server. How should I proceed at this point? I'd like to create my array, migrate existing databases from the single server into a DAG with the two other MBX servers, then remove the CAS role entirely from the single server.
Thank you!

Thank you! Here's the big question: is it possible to move individual databases/mailboxes/domain
Currently: One Exchange server, all roles (with 10 different databases)
Moving to: Six Exchange servers, distributed roles
We'd like to move the clients from the one Exchange server to the 'full featured' setup in a phased approach. Moving everyone at once is frightening!
Is this possible?
Thanks so much!

No issues it is one time command and you need to run at same time for existing db's and for new db's it is not required.
Are you using NLB or HLB for load balancing.

Simon - wow! So you're saying that we can move the databases into the CAS array with zero client impact? Then, as we get to each client, we "repair" or recreate their Outlook profile causing them to point to the new CAS array?
...then, once all the clients are moved over to the new CAS array, we can discontinue the old single server?
One thing I'm not completely clear on...you said, "When you have introduced the new CAS role holders, you can just adjust the DNS entry to point the new server." Our previous clients pointed directly to a server name (internal NETBIOS name). How do we adjust that name to point to the new CAS array? ...or is that not what you mean here?
Thanks again - this is sounding much better than I had originally anticipated!
