Updating an app

[dusker]

Hi,
here's my situation:
i've developed an app that sold pretty well in a certain region, and got a lot of feedback on improving the app, so i decided to do so, but i'd like to start all over again from scratch in order to change the architecture of the app entirely.
And heres my question: is it possible to start from scratch and upload the application as an update to an existing one? if so then how to approach it - sign it with the same certificate as the previous one?

Yes, it's possible. As explained in the Program Portal, as long as you use the same Distribution Provisioning Profile and increment the Bundle Version, it will be handled as an update.

So by using the same distribution provisioning profile you mean signing it the same way i signed the previous app (in project info > code signing identity ) right?

Yup, just follow the steps from the Portal on how to build your app with xcode for distribution.
