Cleaning up Production Elements for Upcoming Canceled Productions

Hello!

I am trying to inactivate Production Elements for upcoming events that have been canceled. In some cases, perfs/prods etc. never have and never will be used and so they can be deleted. However, there are other performances that cannot be deleted because there have been transactions previously associated (but all orders/tickets have been exchanged out of these perfs). I've created a new season (in TR_Season) for COVID canceled productions with fiscal year dates: 03/01/2020 - 08/31/2020. Even when I change the season for the production season, the perfs and production season are still showing as active. 

Additionally, I'd like to inactivate the titles/productions these production seasons/perfs are associated with as they are also no longer relevant. 

Any ideas or suggestions? 

Thanks!
