It provides HA for the MB role. You can collocate all roles on the MB and still use DAG (this is a change from Exchange 2007 HA roles). If you only have four servers and you have to support two sites then your only choice is to have an Edge server at each site and have a multi-role (HT, CA, MB, UM) server at each site.

I am sorry. I don't have the budget to host different roles on different servers. The maximum I can have is 4 servers. 1 each for MB, CAS, Edge & DAG. So basically, I need 1 server with MB. 1 server to host CAS. On which server should I have my HT? on MB server or CAS server? I forgot to add an important point that is, I will be moving to multi site (different geo location) domain with each site having its own MB, CAS, HT & EDGE (for only outbound mails from that site).

Presently, DC Windows 2008 SP2 Exchange Exchange 2007 SP2 (MBX, CAS, HT & UM) on Windows 2003 R2 all role on 1 server. Exchange Exchange 2007 SP2 (EDGE) on Windows 2003 R2 in DMZ across ISA 2006. In the new setup, I would like to introduce coexisting E2K10, move CAS to a separate server. All other roles such as MBX, HT & UM on a separate single server in E2K10. DAG on a different server and completely remove E2K7 from the environment. What all are the roles that is required on Mailbox server and CAS server? How do I achieve this configuration with "0" or minimal downtime?. Any help is much appreciated.
