How to Transfer Operations Master and Seizing?

Transfer operations master In Windows server. Active Directory Domain Services (AD DS) defines five operations master roles. These five operations masters are schema master, domain naming master, relative identifier (RID) master, primary domain controller (PDC) emulator, and infrastructure master. The domain controllers that hold operations master roles are designated to perform specific tasks to ensure consistency and to eliminate the potential for conflicting entries in the AD DS database.

The five operations master roles are assigned automatically when the first domain controller in a given domain is created. Two forest-level roles are assigned to the first domain controller created in a forest and three domain-level roles are assigned to the first domain controller created in a domain.
