Currently it is only possible to test process instance migration between two subsequent minor versions of camunda. It would be good to be able to execute process instance migration tests accross multiple versions of the process engine.

AT:

• as a camunda developer I can start a process instance in a given version of camunda (say 7.2.0) and complete it with a later version (say 7.4.0)

Note:
I (Daniel) have some Ideas how we could make this work ewasily based on the current infrastructure
