Respect process instance migration for running C7 process instances

What/Where is the issue ?

In C7, process instances can be migrated to a newer process version in the engine during their execution. The version displayed on the process instance in Optimize, however, does not get updated until the process instance is completed.

Environment: C7

Optimize version : All
ES version : All
OS + Browser version : All

Steps to reproduce:

• Preconditions:
• Steps:
  • Deploy version 1 of a process and start an instance with multiple tasks (don't complete it - it needs to be running)
  • Observe the data in Optimize in a report filtering for version 1
  • Deploy version 2 of a process and migrate the running instance to v2
  • Observe the data in Optimize in a report filtering for version 1. Observe that it is not present in a report filtering for version 2
  • Complete the instance
  • Observe the data in Optimize in a report filtering for version 2. Observe that it is not present in a report filtering for version 1

Observed behavior:

Running instances that are migrated in the engine are not migrated in Optimize until they are completed

Expected behavior:

Running instances that are migrated in the engine are also migrated in Optimize

Additional Information:

We can get the process definition ID for each of the import DTOs that make up a process instance. Using this, we might be able to determine if an instance has been migrated. It is unlikely that Optimize can know about the migration of a process instance until more data is imported for the instance, so some delays in Optimize might be inevitable.
