Donorchoose, Fist of all, using a workflow engine makes it easier to quickly develop process oriented applications. It does not necessarily make it easier to migrate. If you search the forums in a little detail, you will see that it is not impossible to migrate running instances, but that it is not something that is supported by the jBPM community. Small changes are not that difficult but require db manipulation. Just have a look at how the db structure is and it will become fairly obvious. It mainly boils down to changing foreignkeys. It surprises me you frequently have the need to add/change transitions etc... feels like a very 'ad-hoc' process. If business processes change that often, there is a more substantial underlying problem imo. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4244772#...
