Change High level Board status & Group based on completed tasks in Low Level Board

Hi All,
Apologies if this has been answered elsewhere but I couldnt see a solution tailored to my needs.
We are a video production company and I would like the status & group of my project (In my high level board) to change based on when tasks are completed in the low level board.
In the Low Level board we have multiple tasks that are grouped into: Pre-production, Production, Post-Production, Finished.
When all of the tasks in the Pre-production group are finished, I would like it to change group in my High-level board.
Is this possible? or would I haver to change the group manually in the high-level board.

Hey Rob,

Have you connected those items in items in your low level board and is the status of those items mirrored into the high level board?

Additionally, does your high level board follow the same structure? I.e. is it broken up into the same groups as your low-level board?
