Exchange 2010 CAS Array
Exchange 2010 to Exchange 2010 migration. Our old server is on its last leg and I am replacing it. I am simulating the migration in a lab environment currently.
I have the 1st Exchange server fully built and functional. It is passing email and the Remote Connectivity Analyzer passes all test. I just finished installing the 2nd exchange server and am stuck there.
Should I have already configured the CAS array or should it be done now, before I move any mailboxes or change any other services to point to the new exchange server?
In order to build the CAS array, I have added an "A" record on our internal DNS server and pointed it to a hostname that can not be resolved or connected to externally. The CAS array will NOT be listed on the SAN cert for either of the exchange servers. I am not sure about the Power shell command to build the array though. I think it should be something like the following.
What else do I need to do, to ensure the CAS Array is setup properly?

New-ClientAccessArray –Fqdn “outlook.nhmelab.net” –Site “Default-First-Site-Name”What else do I need to do, to ensure the CAS Array is setup properly?
Command looks good, I usually go with the following:
New-ClientAccessArray -Name cas-01 -Fqdn outlook.yourdomain.com -Site YourSiteName
Load balancing a CAS array is recommended. It is possible to do this for free by using DSN round robin (although this is not really load balancing) or Windows Network Load Balancing - however you can't use WNLB if the CAS members are also located on a server that runs the mailbox role and is part of a Database Availability Group
The following load balancers from Kemp are very good and come as physical and virtual appliances

Just to add you are correct the keep the CAS array name not resolvable externally and off the certificate.
Its always best to set up a CAS array as soon as possible otherwise you will need to update the RPC Client Access Server Attribute to register any existing databases to the new CAS array. This can be done using the following command
Set-MailboxDatabase "DatabaseName" -RpcClientAccessServer "YourFQDNCASName"

Thanks for the quick reply, so really, I should have setup the CAS array before I setup the the 2nd Exchange server. Is that correct?
To clarify, since I did not setup the CAS array prior to setting up the 2nd Exchange server, the "Set-MailboxDatabase "DatabaseName" -RpcClientAccessServer "YourFQDNCASName"" command should now be used to bind the mail stores to the CAS array.
Do I run the above command for each mailstore?
