best way to upgrade to windows 2003

Archived from groups: microsoft.public.win2000.setup_upgrade (More info?)

Hi I was wondering what the best way to upgrade from NT 4.O domain to Windows
2003 domain. What is the best way to move all users account and at the same
time keep the setting (login scripts, profiles, ect) Any software that would
make this process easiers. Is the best way to do it to create a new DC that
is running W3K and then replicate and demote the NT4 DC. This is my first
upgrade and any help advice would be very much appreciated.

thanks for any advice in advance

    To move from NT 4.0 to Win 2k3 you can either upgrade (by upgrading the
    existing PDC first) or migrate by setting up the NT and AD domain side by
    side on the same wire and use ADMT to move users from the NT domain to the
    AD domain.

    You should research each way to decide which works best in your environment.
    You have to make decisions during setup that may take a format and reinstall
    to recover from.

    This will not work. When you realize that the NT 4.0 PDC is the only DC on
    the NT domain that carries a writeable copy of the SAM. Also that Win 2k3
    can not be a BDC, there is no such choice, AD DC operate in multi master
    mode. You will not be able to get a NT 4.0 PDC and a Win 2k3 server in the
    same domain so they can replicate.


    AD totally relies on DNS

    You might also consider removing Win 2k3 from the new server and installing
    NT 4.0 on it as a BDC while connected to your existing domain, promote to
    PDC then follow the above link to upgrade it to Win 2k3.
