Description
autoIndexId:false support was removed in SERVER-8237 for 4.0:
Starting in MongoDB 4.0, you cannot set the option autoIndexId to false when creating collections in databases other than the local database.
https://docs.mongodb.com/v4.0/reference/command/create/
This may cause issues restoring data from previous server versions to 4.0. What should mongorestore should do in this situation?
Update: Answer: omit autoIndexId when creating collections.
