(very) long lasting processes

Hi,

We have business processes implementing important legal procedures that can take more than a year (or several years) to complete. Say we start such process instance today using Activiti 5.5, and we need to upgrade to Activiti 7 in two years from now, in what way could this upgrade impact the running process instances ? Is it possible to assert the risks here ?

I'm thinking things like (in ascending order of disruptiveness)
  1. api changes on the process engine services

  2. deprecated / removed / changed extension points

  3. changes in the database schema

  4. changes in process execution semantics


Anything else ?

We can easily find out and fix 1/2/3 in a test environment, but 4/ will be harder to test against. I'm not asking for a binary-compatibility-guarantee here, just want to get an idea what we are looking at if we decide to implement Activiti for the long haul on this project.

Thanks,
Jorg
