Hi, I administer a child domain in a very large AD forest and during most recent corporate changes my organization will join to the new domain. New domain is already in place and ready. Users and some servers will be migrated. However, I have some local sites and services (SharePoint, IIS and SQL) running in the old domain that we need to keep for a while and there is no plan to migrate those services to the new domain. Is there any problem to keep my old domain running localy without having connection with the forest? - I have 2 local domain controllers (RID master, PDC emulator and Infrastructure master) - no connection with Schema Master and domain naming master Question: Can my child domain survive on its own? I appreciate your input.

Hi, Based on my understanding, you should still be able to access the resource in the child domain if the DNS and GC roles are installed on one of the domain controllers in the domain. Thanks.This posting is provided "AS IS" with no warranties, and confers no rights.

HIMy suggestion here to you if your root DC will migrated to new forest , so the old forest and old root DCs will still remain you will not remove the root DCs after migration it will be helpful But you cant move or demote the root DCs in the forest because it conation all information about your child domain structure and site and services structure for your child domain so you cant keep your domain running without the root DCs Thanks
