Migration from NT to W2k3

    We are planning to do a migration instead of an in-place upgrade so that we
    can collapse two NT4 domains into one domain. Does anybody know of a good
    document that refers to this type of migration. All the documentation I see
    is for an in place upgrade.

    In my testing enviorment I have the new domain setup and ADMT setup, but not
    sure whether I upgrade the BDC's to member servers, upgrade member servers
    or bring over the users next.

    If anybody has any ideas I would appreciate them.

    Thanks
    Greg

  2. Hi Greg,

    I did not find a document discusses this scenario. Based on my knowledge,
    the migration should be similar to migrating a NT domain to 2003 domain. You
    can refer to the following article to migrate each NT domain to 2003 domain:

    HOW TO: Set Up ADMT for a Windows NT 4.0-to-Windows Server 2003 Migration
    http://support.microsoft.com/?id=325851

    The following are some tips or requirements regarding ADMT:

    1. Generally speaking, domain migrations are complicated tasks. Please
    perform complete backup first for recovery purposes.

    2. We can establish a two way trust between the two domains, and then use
    ADMT with the following three wizards to migrate the group accounts, user
    accounts and client computers:

    - Group Account Migration Wizard
    - User Account Migration Wizard
    - Computer Migration Wizard

    3. The account that runs ADMT must have administrator privileges on both
    domains, and also need to be a member of the local administrators group when
    migrating computer objects.

    4. It is recommended to perform the migration in the following order:

    Domain Global Group
    Domain Local Group
    User Account
    Computer Account

    5. Please migrate the groups and users separately (do not migrate the
    associated group members when migrating the groups).

    During the group migration, please use the following configurations

    [Group Options]

    Copy group members * Not Checked
    Fix membership of group * Checked

    During the user migration, please use the following configurations:

    [User Options]

    Migrate associated user groups * Not Checked
    Fix users' group memberships * Checked

    8. For more information regarding ADMT, please refer to:

    information).

    What has me puzzled is when to move all the servers from one domain to the
    other. Both our Accounts and Resources are in the same domain and all the
    documentation points to having an accounts domain and a resource domain.
    Nothing seems to talk about Accounts and Resouces in the same domain.

    I'm using Virtual PC to try and simulate this in a test enviornment. Just
    looking for something that says th recommended order is.

    Thanks

  4. Hi Greg,

    We don't need to consider the Account domain and resource domain in this
    case. We just need to perform the migration in the following order:

    Domain Global Group
    Domain Local Group
    User Account
    Computer Account

    If you still have any questions or concerns, please feel free to let me know.
