Need to convert my Windows Phone 8.1 app code to Windows phone 8

Question

I have developed an app for Windows Phone 8.1 but now I want the same app to developed in Windows phone 8.0. It is possible to do that? Is there any migration tool available or I need to develop from scratch.

Answer 1

No you can't downgrade any app after you've started developing. IF you wanted to develop a WP8 as you said have to start it from the scratch. But still you can upgrade a WP8 app to WP 8.1 (For Silverlight Apps). If it's normal WinRT app you can only develop targeting 8.1 only.

Hope it helps!

Answer 2

You just compile the 8.0 release and upload the *:xap to the store without deleting your 8.1 *.appxupload.

Uppdate App >> Upload and describe your package(s) >> Add new

You might wanna consider making a phone 7 app for best coverage (7 will work for 8.0 users).
