Changing CAS1

Hi, we are in the process of installing a hardware load balancer for Exchange. For right now it is strictly for the internal Outlook clients.

We want to change the address that clients point to internally so we can point that to the hardware load balancer.

At this point we don't want to load balance OWA, Activesync or Outlook Anywhere, those will come later. What do I need to do? My Get-ClientAccessArray command returns this

----               ----                ----                          -------

CAS1                NYC             CAS1.Domain.org            {EXCH1, EXCH2}

I want to create a DNS record named CAS2 and have the Outlook clients point to that instead of CAS1.

Would it be as simple as using the Get-ClientAccessArray command and changing it to CAS2 and creating a DNS record for CAS2 or would it be more than that. I get really confused when reading about this on the web and people start talking about autodiscover, certificates and such.

We currently have Exchange 2010 SP2 RU4 and mostly Outlook 2007 clients but some 2010.

Any help to clarify this would be much appreciated.
