Active Sync logic for migration from 2007 to 2010

I have used iApp f5.microsoft_exchange_2010_2013_cas.v1.2.0 to deploy Exchange 2010.

 

In the DMZ I deployed BIG-IP APM will provide secure remote access to CAS.

 

Then I forward that traffic to a VS on the internal network, setup with the iApp as well. The scenario used s BIG-IP LTM will load balance and optimize CAS traffic. Exchange is working well with this deployment. Both 2007 and 2010 mailboxes work end to end, my only issue is how to integrate active sync.

 

IE. In the test environment exchange.test.com will function properly for 2010 and 2007 mail, internally and externally. Migrating mail will be easy, the only issue I have is that active sync doesn’t work on that single entry point into exchange.

 

I am looking for some logic where I can split that off into 2007 versus 2010.

 

Thanks
