Before attempting to transfer the primary domain naming master role in Active Directory, it is suggested to go through the following steps:

1. Check server requirements, such as the operating system, hardware requirements, and domain functional level.
2. Verify that the account you are using is configured as a member of Enterprise Admins or Domain Admins.
3. Create a connection request to the intended target server.
4. Verify that the domain identifiers and Domain naming FSMO role have the correct values.
5. Reboot source and destination server to ensure no hangs.
6. Run the following command on the source server:
   ntdsutil roles transfer naming master connections connect to server destination server quit quit
7. Wait for the transfer to complete.
8. Use the command: netdom query fsmo to confirm all FSMO roles are pointing to the new server.
