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: abc.com and xyz.com,
both are separate forest abc bought xyz now they want to merge and xyz
doesn't want to change there name i.e. xyc.com to something else. I
understand that I can create a separate name space in the abc.com forest for
example efg.com and use the ADMT to migrate all the accounts and resources
from the xyz.com forest and then everything will be in the same forest, but
my question here is can I keep the same name xyz.com and if I can how do I
do this.

Thanks in Advance

P.S Thanks Matjaz Ladava for helping me with the first part.
 
You can create additional tree in the abc.com forest called xyz.com. 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 xyz.com to abc.com
forest (to separate OU), create additional UPN suffix xyz.com in abc.com
forest, to that abc.com users will retain their UPN. After migration is
completed, you can create new tree called xyz.com and migrate users there
(using movetree command).
How many user accounts are you migrating from xyz.com forest ?
