Our company has two separate domain/forests at 2 different locations connected by a VPN WAN and external trust. Both PDCs are Server2K8R2.
One named A.CompanyName.Internal, the other B.CompanyName.Internal, again both separate domains in separate forests with a external trust.
We want to consolidate the domains so that we can invoke Domain wide DFS for file replication and centralized backups.
What would be the best way to do this? A domain migration from B.CompanyName.Internal to A.CompanyName.Internal is one possibility (a lot of work). Is there an easier faster method? Parent/Child Domain?
