Transferring makes the old DC know that it does not own the role(s) any more. If the DC is broken (e. g. hardware defect) and will never come back again, then you can seize the role on a remaining DC.
What happens if RID Master is down?
If RID Master is down, DC will continue to create objects till the time it consumes all it’s available RIDs. If a DC has consumed all RIDs and RID Master is still down, you will not be able to create any new object in that DC because DC can’t get another pool of RIDs since RID Master is down.
What happens when PDC is down?
The PDC Emulator is the operations master that will have the most immediate impact on normal operations and on users if it becomes unavailable. Fortunately, the PDC Emulator role can be seized to another domain controller and then transferred back to the original role holder when the system comes back online.

What is seize in FSMO?
The process of moving the FSMO role from a non-operational role holder to a different DC is called Seizing, and is described in this article. If a DC holding a FSMO role fails, the best thing to do is to try and get the server online again.
What are the 5 roles of Active Directory?
Active Directory has five FSMO roles:
- Schema Master.
- Domain Naming Master.
- Infrastructure Master.
- Relative ID (RID) Master.
- PDC Emulator.
What will happen if FSMO roles fails?
After the schema master role has been seized, the domain controller that had been performing the role cannot be brought back online. A failed RID master will eventually prevent domain controllers from creating new SIDs and, therefore, will prevent you from creating new accounts for users, groups, or computers.

Verification
- Identify the domain controller that has the PDC emulator role. From the command line of any domain controller, run.
- Verify network connectivity to the domain controller by using the ping command.
- Verify that Active Directory replication is working properly.
- Verify that the PDC emulator role is functioning.

According to Microsoft recommendation, the Best Practice is to split the FSMO roles between the different domain controllers. The forest-wide FSMO roles should be placed on one DC, and the domain-wide roles to another. If you have only one domain controller, it is recommended you to deploy an additional DC.

What is KCC in Active Directory?
The KCC is a built-in process that runs on all domain controllers and generates replication topology for the Active Directory forest. The KCC creates separate replication topologies depending on whether replication is occurring within a site (intrasite) or between sites (intersite).
