Collapse of two domains with same Netbios Name

Discussion in 'Server Migration' started by Alistair Keay, Jun 20, 2006.

  1. Customer has two domains _ One in America and one in Europe with the same
    Netbios name.

    Both domains are small to medium size spanning about 4 sites each with
    approximately 6 domain controllers, exchange 2003 and about 200 users each.

    The aim is to collapse one domain into the other.
    Customer’s idea was to create a child domain for the American domain, then
    create a trust with the European domain and use ADMT to migrate users across.
    I don’t think this is going to work and I would value advice on this and
    any clever ideas to overcome the problem.

  2. if the name is the same you cant migrate them into each other...

    for that you need an interim fomain/forest

    options:
    * migrate both (one at a time) into new forest/domain
    * migrate one to interim forest/domain and then migrate that to other

  3. My only other idea is to carry out a domain rename but I have tried this in a
    lab and it did work but I see this as being very high risk.
