Semantic model (Development and Production version)

Hi,

I have created a semantic model SM in development workspace WD. I want to copy SM to production workspace WP. How to do that? I don't think Power BI has that option. 

If this cannot be done, how do you guys usually manage development of semantic model? We cannot be using the same semantic model for development and production right? It will give problem if we modify the semantic model for development purpose while other production report is connected to it.
