If you upgrade point releases ie. 2.0.0.GA to 2.0.1.CR1 then you can typically just copy over the lib folder and be done with it. The problem with creating an automated script is going from major releases like 1.2.1.GA to 2 GA, in this case the tool would need to update all schemas and namespaces and api in your code. It would be not be a trivial tool to create. To most customers I deal with I recommend just creating a clean project and migrating the old code over. I've see a lot of problems when this is not done, so I am dogmatic on recommending it now, always create a clean project :) And if you feel like tackling a daunting task, feel free to write such a migration tool and contribute it back to the project. -Samuel View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4112727#...
