CAS server to different network

Posted on 2014-10-23
Last Modified: 2014-10-27

I was wondering how I can move my CAS 2010 from one network to another.  I have already created the subnet under the AD site and services.  I am not moving my exchange HUB and Mailbox server just the CAS has to be moved.  The AD site consists of both networks.

I cannot find anything on the internet on this.

That is because you cannot do it.
If you have multiple sites then you MUST have a CAS (and Hub Transport) in the same AD site as the mailboxes. You cannot separate them out.

This normally isn't a problem as best practise is now to have all roles on all servers. Therefore if you are moving the CAS entry point to another site, simply add the CAS role to the hub transport or mailbox role server.

I believe I can do that; have CAS and hub transport server on the same server, but I really don't want to do it.  Please note that both the CAS server and HUb Transport WILL BE on the same AD site.  The AD site will have 2 separate network assign to it.  So, will I have a problem?

It is not recommended to try and dual home a CAS server.
Are the servers in the same physical location?
Changing the IP address of the CAS server isn't a problem, but AD sites and services and the placement of the server is crucial to having it perform well.

Why don't you want to put hub and CAS on the same server? I haven't done a design with the roles separate for over three years - and that includes some of the biggest Exchange implementations in Europe.

OK.  I got it, it is not recommended but possible.  You see, I already have the server.  The server is virtual and I have already configured all the MAPI, POP3, Certificate and all other crap on it.  If I have to add it to my Hub Transport then I have to redo everything, not a big deal but I don't want to deal with it.

CAS takes about ten minutes to configure and I would encourage you to do it that way.
