Migration of "abc.com" to "def.com" and becomes "abc.def.com"

    Hi there,

    I have two separate forests: abc.com (group of 2008/R2 DCs) and def.com (group of 2008/R2 DCs), we wanna move/merge "abc.com" under the forest "def.com" as sub-domain to become "abc.def.com". The main issue is we don't want to affect anything in both forest during migration. (we have over 1000 desktops and 1000 users in total).

    I wanna clarify my migration plan and wish someone can shed some light on me.

    1.  establish a two-way trusts between the forest?

    2. create a new sub-domain under def.com ("abc.def.com"), use ADMT to migrate all of the users/computers/print queue/group policy from "abc.com" to "abc.def.com" by reserving the old SID history. shutdown abc.com afterwards

    Am I correct?

    Thx in advanced

    Simon

    Yes , you can do that but need to check domain nesbios name duplication. it is better if your new domain name like  pqr.def.com

    You can use ADMT migration tool. Please go thought the ADMT guide.  Here are the high level steps and a flow chart:

    Yes you can use ADMT to do it. However, since a trust relationship is required, all domains should have different DNS and NetBIOS names. So, if abc.com domain has ABC as NetBIOS name, you should not use ABC as NetBIOS name for abc.def.com.
