Why do I need to change the IP Address on the New Windows 2003 SBS after migrating from the old Windows 2003 SBS? Can I not use the same IP as the Old Machine, as it will be remove from the Network?

I had planed to migrate Exchange mailboxes from an existing Windows 2003 Small business Server to a new Server that is also running Windows Small Business 2003 using the Exmerge method and use the ADMT to shift AD users and Computers to the new Machine accordingly, following the method Jeff outlined in reference to the above question, but I would like to know why it is needed to change the IP Address since the Old Server will be removed from the network. Please could you let me know your thoughts on this.

Kind regards

    Would you care to provide a link to the "method" you are referring to?  That way I can respond directly to the issue.

    It's not really a requirement to change the IP Address subnet... just something I've done to make sure that EVERYTHING is basically a new configuration so that any legacy issues don't move forward.

    However, my method does NOT use ADMT.  You cannot use ADMT with that procedure unless you use a Swing Server as outlined at  My recommendation was for a network with less than 15 users, I've found that it's just as fast to rebuild the user accounts than doing a migration.  Obviously not ALWAYS true, it depends on your particular situation.

    Hi Jeff

    Tht's fine.
     I believe that would be the best option to start with as The users do not exceed 15. It makes sense.
