To transfer domain-specific FSMO roles, ie RID Master, Infrastructure Master and PDC Emulator, follow the steps below.Open the Active Directory Users and Computers console, right-click the domain and then in Operations Masters. Here, each tab displays the three FSMO roles.

To transfer one of the three FSMO roles to another DC, click Change and confirm your action.

To transfer the forest-specific FSMO Domain Naming Master role, follow these steps.

Open the Active Directory Domain and Trusts console, right-click the icon and then Operations Masters. If you are not already connected to the DC you are about to transfer the role, then you can do so by clicking Change Active Directory Domain Controller in the same menu.

In the same way, you will see who is the current role holder and by clicking the Change button you can transfer the role to another DC.

To transfer the forest-specific FSMO Schema Master role, follow the steps below.

First, in a command-line window with administrator rights, type the following command to register the AD Schema snap-in.

Then, open an MMC console (for example, pressing mmc on the Search or Run), and from the FileAdd / Remove Snap-in menu, add the Active Directory Schema console.

Here, right click on the icon and then in Operations Masters. You will need to be connected to the corresponding DC you are going to transfer the role you can do through the Change Active Directory Domain Controller option in the menu.

As before, by clicking the Change button you can move the Schema Master role to another DC.

Now check the status by using the same command
