Child Domain Migration

Discussion in 'Server Migration' started by Paul Campbell, Jul 24, 2004.

  1. I have two forests. One is all Windows 2000 Active
    Directory and the other is Windows 2003 AD. The 2000
    forest consists of a root domain and two child domains.
    The 2003 forest is a single root domain. I need to do
    one of two things: either move one of the child domains
    to the 2003 forest and configure it as a child domain in
    that forest. Or I can migrate all of the objects from
    the child domain into the 2003 forest root domain. A
    trust exists. The whole function of the 2000 child
    domain is strictly for authentication to an internal
    website that a vendor insisted on putting in a separate

    Does anyone have any ideas on the best course of action?
    I have to proceed very cautiously because this is a
    hospital and access to the internal website is critical.
    What are the pros and cons of each course of action?

  2. Paul-

    I'd suggest using ADMT to collapse the domains if you can. You need to setup
    a test envrionment and test your internal apps against the collapsed forest
    pretty extensively from the sounds of it, though.

  3. Hi Paul,

    Thanks for your posting here and thanks for Brian's reply.

    If you want to move the child domain to Windows 2003 forest as a child
    domain, you need to build up the target child domain first. Then try ADMT
    tool to perform migration. If you prefer to migrate to the root domain, you
    can just migrate directly.

    I believe the following documents will be helpful.
