[jboss-user] [JBoss jBPM] - Re: Is it possible to update a process def without versionin

[jliptak]

I personally think it's probably a mistake to try and do too much auto-conversion.  I think time would be better spent on an export-import feature.

You could then:
a.) export the running instance to say XML (which removes the instance from the database).
b.) edit (if necessary) the exported data to match the new process
c.) import the running instance against a different process version.

This has some advantages:
1.) it would allow batch processing of the upgrade
2.) strange migration rules could be implemented in something like XSLT
3.) you could choose which instances to migrate.

As long as you don't have any jBPM -> business table foreign keys it should work just fine.
