2010 Coexist 2007


  • I attempted to do a coExisit 2010 with 2007.   Below is a diagram of the setup. 

    I am unclear, if I need to create an Internal DNS record called Legacy.domain.com, and it if plays a role.

    My objective, is move Internet Facing 2007 CAS in AD site 1,  to 2010 CAS in AD site 2 (making it the New Internet Facing Site, it also has a 2007 CAS in this site. 

    When I attempted the coExist, I wasn't able to proxy to 2007 CAS in AD Site2.,  But I was able to for the 2007 CAS AD Site 1.

    Thank you for your help.

  • Hi

    Have you done these steps:

    1. On the CAS2010 server(s), they establish a connection to the CAS2007 server's drive that contains the Exchange binaries and navigate to the \Client Access\OWA directory (e.g. \\cas2007nonIFAD\c$\Program Files\Microsoft\Exchange Server\Client Access\Owa).
    2. They then copy the highest version folder (e.g. today your SP2 build is from the CAS2007 server to the CAS2010 Exchange binaries \Client Access\OWA directory (e.g. C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa).
    3. They then execute IISReset on all the CAS2010 machines.

  • Thank you for your Reply.  I did copy the Binany Files,  but does it matter which 2007 CAS I copy it from ?

    In the diagram above, under NEW.   I copied the Binary Files of the CAS 2007 in AD Site 1 , into CAS 2010 in AD Site 2.    Both  CAS 2007 AD Site 1, and CAS 2007 AD Site 2, have the same ver (8.3 build 8.6).

    Does Legacy.Domain.com  still play a role in this setup ?

    Thank you
