Hi prm22mis,
Domain functionality enables features that will affect the entire domain and that domain only.
You can raise the domain functional level on the primary domain controller (PDC) emulator operations master only. The AD DS administrative tools that you use to raise the domain functional
level automatically target the PDC emulator when you arise the domain functional level.
Forest functionality enables features across all the domains within your forest.
You can raise the forest functional level on the schema operations master only. Active Directory Domains and Trusts automatically targets the schema operations master when you raise
the forest functional level.
