Transfer Data from one game to another (different universe)

Im trying to transfer a DataStore from one game to another (different universe). I know that you can try to transfer all the values ​​to a DataBase or try to get all the values ​​​​in the DataStore and convert them to JSON, but often I get the error “ListKeysAsyncThrottle”. I would love to know if anyone here has done this before and can give me answers.
