We would like to migrate from Exchange 2003 to 2010 by doing the following configuration:
1:1 NAT public IP to the CAS array IP
2 servers - > with CAS (WNLB) and HUB configured
2 servers -> MBX with DAG
Anyone running something like the above scenario in a production env.? For the scenario above what is going to be the downside of not using a TMG server?
