  • Help in Domain Restructuring

    Hello,
    We are in the process of restructuring our domain 2003 Native Mode to Windows AD DC 2008 or persevere the 2003 AD.

    Current Scenario:
    1. Two DCs 2003 R2 SP2 with SINGLE-DNS-NAME
    2. One Exchange 2003 migrated from Exchange 5.5
    3. 800 Users including 26 Branches connected via Leased Line to HQ Office.
    4. 130 various Members Servers


    Looking forward to build a Cluster Exchange 2007 but since it's not supported with SINGLE-DNS-NAME, I have those options in my mind and I would like to share it with you and get your opinions;

    Option 1:
    1. Build a new 2008 Forest with FQDN Name to support Exchange 2007
    2. Install Fresh Exchange 2007 in the New Forest
    3. Create both way Trust between both forest
    4. Migrate AD objects using ADMT v3.1 to support Windows 2008
    5. Move Mailboxes from Exchange 2003 to the New Exchange 2007 in the New Forest
    6. Decommission Old 2003 DCs and Exchange 2003



    Option 2:
    1. Renaming the existing Forest from SLD to FQDN
    2. Build Exchange 2007 in Cluster Mode
    3. Migrating Exchange 2003 to Exchange 2007
    4. Move Mailboxes
    5. Uninstall Last Exchange 2003


    Your opinions will be highly appreciated.

    Create a copy of some of your network in a test environment and try renaming the domain maybe?

      Hello,
      Off course this practice will be done in test environment, applying it on our T&D environment and lastly on the production.

      But does that mean renaming the domain and retain everything in-place is better than building a new forest with freshly installed exchange 2007 cluster and migrate users using ADMT along with the Mailboxes to the new forest!!

      I think this option is appealing as it's will not carry DNS problems from the old domain , secondly we are migrating to the latest supported version of Windows AD and Exchange system.

      Any thoughts?

        How bad are the problems? I wouldn't look at renaming or migrating until I had settled AD first (at least as much as possible).
        Personally I would go the rename route assuming all worked well in a lab but that is just my opinion.

          HI Andy,

          The problems are bad as long as they are struggling me, you and every Administrator . I will rethink of both options and I will try to stay away of renaming as most of our core applications they work only via the NetBIOS name. So, we accept login porblems but we don't accept core application down and money lost. That's why Migrating to a new forest is much better as the migration will be slowly, for group of users and lastly the servers. So, we can eliminate the problem where is strike.

          Hope you are agree with you
