Moving FSMO roles
In the Active Directory setup, sometimes, FSMO roles will need to be moved from one domain controller to another. Here, I have listed a few scenarios where it will be necessary to consider FSMO roles transfers:
- Active Directory upgrades: When there is the requirement for an Active Directory upgrade, first we need to introduce the new domain controllers to the existing setup and then move the FSMO roles. After that, the domain controllers that run older versions can be decommissioned.
- Active Directory logical and physical topology: When installing the first domain controller in the infrastructure, it will automatically hold all five FSMO roles. But, based on the Active Directory topology design, the roles can be transferred to ideal locations, as discussed in the previous section. This can be based on the initial design or an extended design.
- Performance and reliability issues: FSMO role owners are responsible for specific tasks in an Active...
