Hi Kenneth,

We only support mixed mode operating system enviornments during a rolling
upgrade scenario and not for a long extended amount of time like months or
years.

811272 How to Perform a Rolling Upgrade of Windows Server 2003 Server
Clusters
http://support.microsoft.com/?id=811272

Simply because for Cluster Services to be highly available and supported,
we require all firware, drivers and components be the identical as
mentioned in the article below:

828262 How to locate qualified cluster solutions for Windows
http://support.microsoft.com/?id=828262

But we allow a very small amount of deviation in Windows Server 2003
mentioned in the article below:

814607 Microsoft support for server clusters with 3rd party system
components
http://support.microsoft.com/?id=814607

Hope this helps,
