Hi cenk1536,
As you said, you created two separate controllers (work as 2 versions) on same Web API project, if these two controllers/endpoints work well locally and you setup IIS configurations correctly, your API application should also work on IIS after you deployed
the project to your IIS server. If you have further questions about your Web API project, please feel free to post back.
Besides, if you have problems/questions about setup IIS, you can post the questions in IIS forums.
