wp8: how to submit an update to the app in windows phone store?

Question

I have already submitted an app (v1.0) now i wanna update my app. here, i got confusion. There in the windows developer center, two options are available.

Replace or Add New . Which one I should give to update my existing app ?

Answer 1

To update your app, you should use Replace .

Add new allows you to associate multiple XAPs with the same app GUID (for example, if you want to publish two different binaries for a single app: a WP7 version and a WP8 version).
