certificate - Remove iOS App that is Ready For Sale -

My question is simple: Is it possible to remove my app from iTunesConnect, which is ready for sale?

I've submitted a buggy app and want to update it using various mac. By mistake I did not back up my certificate and other important stuff from my old Mac. So I think the only workaround is to present a new app using different bundle names and SKUs. The problem is whether to remove my existing app from iTunesConnect, which is ready for sale?

In iTunes Connect,

• Manage your apps
• (the app you want to delete)
• Right & amp;
• Unselect all countries
• Save

  This will remove it from sale.
