  • Hi Dev,

    Based on your current server versions, it is available to install Exchange 2010 co-existent with Exchange 2007.

    For more details to understand how proxy and redirection work, we can refer to:

    Exchange 2010 SP3 can co- exist with exchange 2007 SP3 RU6 for CAS-CAS proxy? else do we have to update exchange 2007 SP3 RU6 to RU10 (latest versions)?

    Hi,
    The latest Rollup for Exchange 2007 SP3 is RU11 and YES, it would be a good idea to install it before you patch your Exchange 2010 Server(s). RU7 is a bit old now.

    If you don't you will probably see CAS-CAS Proxy problem that was fixes in RU7.
    See: Exchange 2010 SP2 RU1 and CAS-to-CAS Proxy Incompatibility
