Upgrade a cluster from Windows 2000
If you are upgrading from Windows 2000 to Windows Server 2003, Enterprise 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.
The following topics describe the processes and procedures for upgrading from Windows 2000 to Windows Server 2003.
