For this proposal, I think the following timeline is achievable:

Milestone 1 (approx 7 days):  Get overview of the jBPM codebase and learn the build system.

Milestone 2 (approx 12 days): Work out the simplest possible example and discuss the proposed solution.  Starting points: add a property to the deployment (probably as an attribute in the process definition).  Add process instance migration code to the JpdlDeployer.    

Milestone 3 (approx 7 days): Add a translation map in case activity names have changed.  Define how this mapping information will be part of a deployment.

Milestone 4 (approx 15 days): Analyse exact constraints for migrating process instances over to a changed process definition.  What kind of changes can be handled.  And what kind of changes cannot be handled.  Add those constraints to the process instance migration.

Milestone 5 (approx 15 days): Develop a testing strategy for process instance migrations.
