FIX: Cluster upgrade to SQL Server 2008 fails when SQL Server 2005 cluster nodes have different installed features

Consider the following scenario:

• You install a clustered instance of Microsoft SQL Server 2005 in a cluster environment.
• On one node of the cluster, you add a feature of SQL Server 2005. For example, you add Reporting Services or Analysis Services on the node.
• You do not add the feature on all the cluster nodes that host the instance.

In this scenario, when you try to upgrade the clustered instance of SQL Server 2005 to SQL Server 2008, you receive the following error message:

The Setup program tries to make sure that the features on all the nodes have the same instance ID. However, across the nodes, the Setup program interprets the instance ID for the installed feature as different from the instance ID for the missing feature.

The fix for this issue was first released in Cumulative Update 1.

To work around this issue, remove the mismatched features of SQL Server 2005 that are installed in the cluster environment. Then, run the Setup program again to upgrade the clustered instance of SQL Server 2005 to SQL Server 2008.
