Not all resources are migrated from a Windows Server 2003-based failover cluster to a Windows Server 2008 R2-based failover cluster

When you migrate a Windows Server 2003-based failover cluster to a Windows Server 2008 R2-based failover cluster, only some file share resources that were in the pre-migration report of eligible resources for migration are migrated to the Windows Server 2008 R2-based failover cluster.

After a migration process, the final migration report indicates that all resources that were eligible for migration were successfully migrated. However, only some file share resources that were reported as migrated successfully are present if you check the Failover Cluster Management Microsoft Management Console (MMC) snap-in of Windows Server 2008 R2, or if you check the cluster registry hive under HKEY_Local_Machine\Cluster.

Note If you migrate from a Windows Server 2008-based failover cluster to a Windows Server 2008 R2-based failover clusters, or if you install the Failover Cluster feature on a computer that is running Windows Server 2008 R2, the pre-migration and final migration reports reflect the correct status of the migrated resources. Additionally, the resources that are in the final migration report are present in the Failover Cluster Management MMC snap-in and in the cluster registry hive.

To work around this issue, use one of the following methods to complete the migration.

Method 1

Migrate from a Windows Server 2003-based failover cluster to a Windows Server 2008-based failover cluster. Then, migrate from a Windows Server 2008-based failover cluster to a Windows Server 2008 R2-based failover cluster.

Method 2

Use the Microsoft File Server Migration Toolkit 1.2 to migrate the file share resources.

Method 3

Manually re-create all the missing resources by using the Failover Cluster Management MMC snap-in.

Note None of the workarounds support the migration of any third-party resource types in the cluster.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

However, a Windows Server 2008-based failover cluster cannot be used to migrate settings from a Windows 2000 Server-based failover cluster, or to import settings from another failover clusters that is running Windows Server 2008.
