Hi, making a field mandatory will not have impact as you are concerned.

Only thing can happen if you make a field mandatory now, it will be mandatory for legacy data (records created before you make it mandatory). It is no issue, just to inform you - imagine an example incident form have 1000 records created, now you will make a specific field (e.g. Category) mandatory, it will require being mandatory even for the incidents created before, so if proceeding with the lifecycle it might require additional actions.

But it is nothing to worry from the upgrade perspective. The upgrade is challenging with the scripts, widgets, etc.
