Upgrade

[MLepley]

Before upgrading AD in a windows 2k forest the following commands need to
implemented on the Schema master and all other FSMO master roles computer.



adprep /forestprep



adprep /domainprep



After doing so, is it mandatory to upgrade the existing DC's before
introducing a NEW DC running window 2k3 (DC/GC).



Thank you.

adprep /domainprep

First, You don't have to apply these commands on all FSMO role holders -
forestprep needs to be done on Schema master and domainprep has to be
done only on one DC in each domain.

After doing so, is it mandatory to upgrade the existing DC's before
introducing a NEW DC running window 2k3 (DC/GC).

No, You can introduce it in any moment after preparing forest\domain.
If You have Exchange 2000 deployed in Your network remember about
installing inetOrgPerson fix before doing windows 2003 forestprep.

Maybe You find these few word useful:
