Pruning a child domain to its own separate forest

    We have a mixed mode forest with one "empty root" domain and two child
    domains. We are exploring the possibility of "pruning" one of the child
    domains out of the forest and having it become its own standalone forest. Is
    this supported? Do I need 3rd party tools for this?
    Thanks,
    Tim

    No "prune or graft" functionality such as you state currently exists. You
    need to use the ADMT tool or third-party one such as those offered by NetIQ
    or Quest to migrate that child domain into a new domain/forest.

  3. As Todd stated, it's not supported, but is possible if you take the entire
    forest with you. That is, a child cannot exist without the root (or any
    parent), but you can severe a forest in two if they will never again need to
    be connected (and you have different web and e-mail domains). For example,
    assume the following setup:

    Three domains, a.com,b.a.com and c.a.com. A is the parent, B and C are
    children. You can take a couple of DCs from C and one from A into a
    different environment and then metadata cleanup the missing DCs and the B
    domain. You then have a functioning forest of A and C.

    However this isn't supported, and doesn't really help if you want to branch
    off. The best bet would be to migrate the objects you want and need into a
    new domain (in a new forest).
