I'm in the middle of setting up a Exchange 2013 and Exchange 2007 coexistence. My current Exchange architecture looks like this:
Exchange 2007
MKE Site:
Ex-CASHub01 - CAS/Hub transport
Ex-CASHub02 - CAS/Hub transport/Active Sync
Ex-MBX01 - mailbox server
Exchange 2013
LA Site:
LA-CAS01
LA-MBX01
LA-MBX02
MKE Site:
MKE-CAS01
MKE-MBX01
MKE-MBX02
Resources online I've found show that when configuring virtual directories for Exchange 2013 to provide the identity of my 2013 CAS server but I have two. Do I configure that on both 2013 CAS boxes? Also, when configuring the legacy namespace and creating the DNS records, am I to assume that I need to create 2 host A records for my 2013 CAS boxes to point to my "MAIL" record?
Here are the online resources I'm following to guide me:
