Upgrading to Windows Server 2003, Enterprise Edition, and Windows Server 2003, Datacenter Edition on cluster nodes

If you are upgrading from Windows 2000 to Windows Server 2003, Enterprise Edition or Windows Server 2003, Datacenter Edition on cluster nodes, you might be able to perform a rolling upgrade of the operating system. In a rolling upgrade, you sequentially upgrade the operating system on each node, making sure that one node is always available to handle client requests. When you upgrade the operating system, the Cluster service is automatically upgraded also. A rolling upgrade maximizes availability of clustered services and minimizes administrative complexity.

If you are upgrading from Windows NT 4.0, Enterprise Edition to Windows Server 2003, Enterprise Edition on cluster nodes, you cannot perform a rolling upgrade. For more information about how to perform an upgrade from Windows NT 4.0, Enterprise Edition, see Upgrade a Cluster from Windows NT 4.0.
