Hi again, another question about the expiring relationships - How do I properly migrate from my old schema that didn't have expiration on anything, to my new schema which now has expiration on most things? When I tried to just write the new schema, I'm seeing errors that SpiceDB is attempting to remove each of the object definitions where I modified a relation to now use expiration. I assume it is doing a delete and then write, and the delete is failing because relationships still exist. It would be desirable to not have to delete all of the relationships on production to migrate the schema, is there another way?
