Suppose I have a process(v1), that has a task waiting for an event to be received. Now, I develop version 2 of the process and deploy it. I want the older and newer version of the process to be able to consume the kafka events . But what we came to know is that when we deploy newer version , older version will remove the event subscription and hence the pending task of process(v1) wont consume the event .

Is there any solution for this problem?

Or is there any design change that we need to do?
