How to convert / copy OData V2 project to V4

Hello,

We have one requirement to create OData V4 service. There are 190 entity sets (tables) . OData V4 project does not allow to import model from EDMX file or refer RFC/BOR object or DDIC structure. I have created a V2 project and there I have all those 190 entity sets. But I am not able to copy all entity sets and properties from there as well.

Is there any easiest way to convert / copy Odata V2 project to V4 one ?

Do I have only one option to manually copy / create all those entity sets there ?

Thanks & regards,

Vikrant.
