    Currently I have Exchange 2KEnt and Veritas BU Exec running on the same
    overutilized/under spec'd box. I am in the process of buying a new server
    and will be installing 2003 server Ent. edition and will be purchasing
    Exhange 2003 Ent edition to install. I will need to migrate the Exchange 2K
    data over to the 2K3 box. The existing box is also a DHCP Server, DC,
    alternate DNS and a GC.

    What is the best migration path to take?

    There are three other 2K DCs on the domain as well. The plan is to upgrade
    those to 2K3 standard.

    Your help is greatly appriciated.

  2. Hello Tina,

    Good to hear from you.

    According to the message, I understand that you want to migrate to
    Exchange2k3 environment and upgrade the existing win2k DCs to win2k3. Is
    this correct?

    Please understand that this newsgroup mainly focus on the migration of the
    Windows part. As for the Exchange part, I would like to suggest that you
    post in the microsoft.public.exchange.setup newsgroup since they are the
    experts in Exchange and will provide the most accurate information on this

    As for the Windows part, since you want to in-place upgrade the existing
    win2k DCs, the process is as follows:

    1. Perform a full backup before you take any action.

    2. Run "ADPREP /FORESTPREP" and "ADPREP /DOMAINPREP" to upgrade the
    existing Windows 2000 forest and domain to ensure that they contain the
    additional objects, attributes and permissions necessary to support the
    Windows Server 2003 Active Directory environment.

    3. Perform an in-place upgrade.

    Please refer to the following article for more information.

    In addition, I would like to suggest that you perform Exchange migration
    first. Please do not install Exchange2k3 on a DC, this will bring up
    certain issues.

    If you have further concerns regarding the Windows part, please feel free
    to get in touch. As for the Exchange part, please contact the experts in
    Exchange queue. Thanks for your understanding.
