Well before I read your post I managed to find this: http://calebpowell.blogspot.com/2009/06/jbpm-migrations-our-approach.html So it appears Caleb Powell's team has come up with a tool they're using internally. That's precisely the sort of tool we would need. Without this, our workflows are stuck 3 years out of date and getting worse. I left a note on his blog encouraging them to release the code. Perhaps if you guys prodded them as well we might be able to get that code open sourced. Even if the tool set is limited and/or semi-manual it would be a huge improvement over the current system of having no way of migrating running process instances at all.
