Hi,
Good Day!!
We are planning to do an Active Directory Migration.
The scenario is: parent.local,child1.parent.local,child2.parent.local
Parent.local is having all domain controllers with Windows Server 2012 R2
Child1.parant.local is having one domain controller as windows Server2008R2 and the other one is Windows Server 2003.
Child2.parent.local is having all the domain controllers in Windows Server 2003.
An Exchange organization is present in the forest. But separate AD accounts are created in the parent domain for child domain users for assigning mailboxes. So in effect child domain users have separate account for logon and authentication in their respective child domain and an additional account is present in parent domain for email purpose.
Now the customer is planning to merge all domains together.
Customer conditions:
Customer wants to retain the account in the parent domain for all users. All existing permission on their file servers which is currently in child domains need to be retained. users profile data should be retained with all relevant permissions after the migration.
Could you please suggest the best practice to get it done.
