How can prepare a Single Forest (single domain) environment for Exchange server 2003 and Exchange server 2007? RRS feed

  • Question

  • Existing Environments:

    I have installed Exchange Server 2003 with domain "VCSL4.LOCAL" on server machine "MAIL4" and

    also prepared another environment for Exchange Server 2007 with another domain "VCSL74.LOCAL" on another server

    machine "MAIL74".

    Desired Environment:

    Now I want to prepare an associated domain controller for both Exchange Server 2003 and Exchange Server 2007 by

    residing both Exchanges in a Single domain of Exchange Server 2003 that is "VCSL4.LOCAL".

    Please help me to way out that how can I do this activity by using above existing environments.

    NOTE: Currently there is no user account/data generated in both Exchanges.

  • In order to deploy Exchange 2003 and Exchange 2007 into the same domain you have to Deploy Exchange 2003 first.  This is because once Exchange 2007 is deployed Exchange 2003 can no longer be deployed in that domain.

    The requiremends to deploy Exchange 2007 is that your Schema Master must be W2K3 SP1, and all GC in the site must be W2K3 SP1.

    MS has a great link on how to prep and deploy Exchange into a Domain: http://technet.microsoft.com/en-us/library/aa995902.aspx.  To deploy Exchange 2003 you can see the deployment guide here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&familyid=77b6d819-c7b3-42d1-8fbb-fe6339ffa1ed

    So, first as a member of the Schema Member you will want to deploy Exchange 2003 schema objects and then prepare the domain.

    Once the forest and domain are preped install the first Exchange 2003 server.

    Once 2003 is deployed you can prep for Exchange 2007 SP1 by doing a setup /PrepareAD.  Setup PrepareAD with Exchange 2007 SP1 will prepare the legacy exchange permissions, prepare the schema and prepare the domain. 

    This will give you an environment with both Exchange 2003 and Exchange 2007.
