Thanks for posting in Microsoft MECM Q&A forum.
May we know if you have two seperate MDT environment, non-productive Enviroment and productive Enviroment?
==>1.Can i create the Image in a test/non-productive Enviroment with Evaluation Version of Server 2016 and licensed Windows 10 ISO Image from VLSC for productive use?
Based on my experience, yes, you can.
==>2.Will there be Problems when i use only the same Domainname as on Productive Server not actually the same Domain because test/non-productive Enviroment?
Based on my experience, we should capture our reference image on a workgroup computer. And then we use a Domain Join Step into the Task Sequence to join your domain when deploying the operating system.
Thanks for your time.
