HiIf i have a deployment with a process (process1) containing a CallActivity starting another process (process2) then deploy a new version of these processes, what will the existing process instances of process1 start when reaching the CallActivity starting process2.

A call-activity by default, calls the latest version of the process that is configured in "calledElement".

What are the possibilities for having it call a older version?

 public void execute(ActivityExecution execution) throws Exception {
    
 String processDefinitonKey = this.processDefinitonKey;
    if (processDefinitionExpression != null) {
      processDefinitonKey = (String) processDefinitionExpression.getValue(execution);
    }
    
    ProcessDefinitionImpl processDefinition = Context
      .getProcessEngineConfiguration()
      .getDeploymentManager()
      .findDeployedLatestProcessDefinitionByKey(processDefinitonKey);
    
    PvmProcessInstance subProcessInstance = execution.createSubProcessInstance(processDefinition);

You'll have to extend the CallActivityBehavior to use, for example, a fixed processDefinition ID instead of a key in the field processDefinitionExpression (which corresponds to the BPMN calledElement). You can easily alter the ActivityBehaviorFactory used by the latests parser in order to accomplish this. If you're not able to wait for the 5.12 version, you'll have to use a BPMNParseListener and replace the ActivitiyBehaviour yourself when the process us parsed.
