Data Migration from Development to Production in CloudKit for TestFlight Testing

I've developed an app utilizing substantial data uploaded to a CloudKit record in the development environment. Having deployed the Record Type schema to production and released a TestFlight version for testing, how can I transfer the data from the development to the production environment, or upload the data directly to the production environment? This is crucial as TestFlight testers can only access data from the production environment.
