Will my Windows 8.1 app work on Windows 10?

Question

I have a Windows 8.1 app that was developed with the intent of being sideloaded on a tablet as a Line-of-Business application. The client decided to go for the specified tablets but with Windows 10 as an operating system. Will my app still work? This link seems to suggest that I need to do some kind of porting. I assume that I would also have to upgrade my Visual Studio to 2015 since I am currently on VS2013 and that cannot create Universal apps.

Any suggestion would be greatly appreciated.

TIA, Eddie

Apps built for Windows 8.1 run fine on Windows 10 devices, but to take advantage of the many new features in the Windows 10 platform or to extend your app to run on additional device families, you'll need to migrate them.

That document just tell us it will be easy to port a Universal/Windows/WP 8.1 app to UWP:

If you have a Universal 8.1 app—whether it's targeting Windows 8.1, Windows Phone 8.1, or both—then you'll find that your source code and skills will port smoothly to Windows 10.
