Hi, when we publish our code as a set of samples, you should be able to take them and use in production.
It is not possible to update our CTP license, since the CTP does not meet the bar of a product that could be put on a production system.
By using our code however, you can review it and test it to make sure it meets the bar you set for your production system, and you will also be able to make changes if you find issues.
thanks
