Set Task to belong to another process in Camunda

Question

I have process 1 and task 1 started for that process. I have process 2 and task 2 started for that process.

Is it possible to set task 2 to belong to process 1?

What I tried is the following:

mergeTicketTasks.forEach(task -> ((TaskEntity) task).setProcessInstanceId(baseTicketId));

and it is updating the process instanceId of the task but when requesting a list of tasks for process instance 1 I am not getting task 2. Additionally I am not able to see task 2 in the Camunda UI anymore.

So to summarise is it possible to make a task to belong to another process?

How about cancelling the instance of task 2 in process instance 2 and starting an instance of task 2 in process instance 1? This can be done using the process instance modification API: https://docs.camunda.org/javadoc/camunda-bpm-platform/7.17/org/camunda/bpm/engine/runtime/ProcessInstanceModificationBuilder.html
