Consider the following scenario in a Windows Server 2008 domain. You have various domain controllers that are located outside of the organizational unit’s (OU) default domain controllers. You try to migrate the SYSVOL share from the File Replication Service (FRS) to the Distributed File System Replication (DFSR) service. To do this, you use the Distributed File System (DFS) Replication service migration tool (Dfsrmig.exe). In this scenario, the SYSVOL share migration process fails, and you receive the following error message:
The parameter is incorrect.
Additionally, the following event is logged in the DFS Replication log on the primary domain controller (PDC) emulator master:
Log Name: DFS ReplicationSource: DFSR Event ID: 8028 Task Category: None Level: ErrorKeywords: Classic User: N/AComputer: computer name Description:DFSR Migration was unable to transition to the 'PREPARED' state for Domain Controller domain controller name. DFSR will retry the next time it polls the Active Directory. To force an immediate retry, execute the command 'dfsrdiag /pollad'. Additional Information: Domain Controller: domain controller nameError: 87 (The parameter is incorrect.)
This computer name placeholder represents the name of the computer on which this issue occurs.
This domain controller name placeholder represents the first domain controller on which this issue occurs.
The error occurs because the DFS Replication service migration tool does not expect domain controllers outside the OU's default domain controllers. Therefore, the DFS Replication service migration tool does not create DFSR replication member objects for these domain controllers.

Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.
6.0.600 1. 22xxx
Windows Server 2008
6.0.600 2. 22xxx
Windows Server 2008
Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.
The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 SP2" section. The MANIFEST files and the MUM files, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
For all supported x86-based versions of Windows Server 2008
For all supported x64-based versions of Windows Server 2008
To work around this issue, put all domain controllers into one OU (such as the default OU) for the migration to DFSR.
