Windows Server 2008 R2 includes a Best Practices Analyzer (BPA) for all major server roles, including Failover Clustering. This analyzer examines the best practices configuration settings for a cluster and cluster nodes. The test runs only on computers that are currently cluster nodes.
Administrators can migrate cluster workloads currently running on Windows Server 2003 and Windows Server 2008 to Windows Server 2008 R2. The migration process:
Supports every workload currently supported on Windows Server 2003 and Windows Server 2008, including DFS-N, DHCP, DTC, File Server, Generic Application, Generic Script, Generic Service, iSNS, MSMS, NFS, Other Server, TSSB, and WINS.
Supports most common network configurations.
Does not support rolling upgrades of clusters. (Cluster workloads must be migrated to a new cluster running Windows Server 2008 R2.)
