Thanks. What I don't know is how the OrgUnitLevel would react - we'll need
to update those too. I think they are linked through a simple number (and
not a foreign key to the level table), but I may be wrong.

The script you shared is about deleting all data linked to a specific org
unit, right ? Not sure how it related to levels.
