I have given a task to get information on domain migration,
We have windows 2003 DCs with 1 parent xxx.com and 10 child domains yyy.xxx.com. We have about 1600 users in parent and child domains. At least 80 Security and Distribution groups in each domain.
We are planning to get rid of child domains and keep only 1 parent domain as xxx.com
I need your suggestion weather we should collapse the existing child domains and use xxx.com as new domain environment or create a new domain environment using a new name like zzz.com & create 1600 users but I am sure we don't have to create a lot of groups
I spoke with consultant and they are advising to create new domain environment zzz.com.
Reason they are giving is, new domain will not have the attributes from windows 2003, that they believe could affect the performance of the new domain environment.
