Migration of a .NET WebAPI to .NET Core

Guys, I have this WebAPI project:

• .NET Framework 4.6.1
• C#
• Entity Framework 6.1.3 (SQL Server)
• OWIN with custom User entity implemented
• CORS (is made me cry to configure)

This is mainly used by a Angular 1.x application.

What do you thing about migrate this project to .NET Core? Is it able to manage a production software already? What will be the breaking changes?

Thanks!
