business model

Hey guys,
I created a table like in the "getting started tutorial": https://www.bonitasoft.com/resources/videos/getting-started-tutorial?des... and everything works fine.

But now I want to get my table filled not with items via one filter, but with two.
So the actual code looks like this and its working:
../API/bdm/businessData/com.company.model.ManuskriptEinsenden?q=findByUserAndStatus&p=0&c=10&f=userId={{session.user_id}}&f=status=abgelehnt

From my understanding The portal treat each version of a process as a different one, but what happen if I decide to change the business model for one of the process version, let´s say I´m in a production environment and I got a process A then I decide to upload a new version of process A (A.1) but it have a slightly different business model is there a way to work with both business model together or the importing process will overwrite the old business model...?
