Hi:
We are also looking for similar migration from 3.x to 5.x. Looking at lot of discussions and pages that are published for migration, i see there was lot of  efforts been  put in getting this migration easy and it is WIP. It looks like we need to wait for some more time if we have to use the current tools in production environment.

Few open questions i still have is
1. We have the current customers on JBPM 3, If we migrate to JBPM 5, as per my understanding they still can run the old process instance using the jbpm3 api’s, if they start creating a new workflow using JBPM5 then we need to call the new api’s for execution purpose. Or is there any abstract class that does this automatically based on the ProcessDefinition/Process id that is passed or should we do this internally in the programs of JBPM.
2. Will it be possible for us to do the data migration from jbpm3 to jbpm4 by comparing the database structure so that we will have only one version of workflows that we need to deal with or will it be a waste of time to invest based on the amount of change you had introduced in jbpm4/5.

Any help is appreciated.
Thanks
