Too bad WAS 6 can't be automated!! But for the rest of you, attached is a good user story of a client that did do the upgrade using UCD. Quick excerpts here:
“What one senior engineer was able to do with uDeploy, and the WebSphere Application Server plug-in in 3.5 days, would have taken at least eight people and about 1-2 weeks to complete the same task.”
"Reduced total build time for 48 IBM WebSphere cells, including configuration and ensuring consistency between environments, from about 3 months to 6.5 full-time equivalent (FTE) days."
Also, for those that are not UCD clients, did you know you can get a cheap annual license, do the conversion and then stop using it?
Lastly, below are links to two videos (overview and more detailed), also a link to step-by-step instructions.
Short video, migrate to WAS v9

Hope that helps!
