Merging Two Forest into One


Frank A, Zanotti

Hi All,
This is the second part of a question that I didn't ask yesterday, it
has to do with the merging of two forest. Scenario: and,
both are separate forest abc bought xyz now they want to merge and xyz
doesn't want to change there name i.e. to something else. I
understand that I can create a separate name space in the forest for
example and use the ADMT to migrate all the accounts and resources
from the forest and then everything will be in the same forest, but
my question here is can I keep the same name and if I can how do I
do this.

Thanks in Advance

You can create additional tree in the forest called The
problem will be with the DNS servers, which will host the same domain on
different DNS servers (in new domain and in old domain).
One way would be to migrate (ADMT) existing users from to
forest (to separate OU), create additional UPN suffix in
forest, to that users will retain their UPN. After migration is
completed, you can create new tree called and migrate users there
(using movetree command).
How many user accounts are you migrating from forest ?
