Error when upgrade WP7 project to WP8 using VS2012

When I try to upgrade my current WP7 project to a WP8 version using VS2012 built-in feature "Upgrade to Windows Phone 8.0"

I received an error message:

Upgrade to the project could not be completed. Object reference not set to an instance object.

This error has little useful information to work with, how to solve it?

If you want run app in WP 8 devices, perhaps you'll have a problem with the screen resolution on devices HTC. The best way is create new WP 8 project and share (add as link) most of the .cs and .xaml files of your WP7 project. I did it guided by the article http://www.developer.nokia.com/Community/Wiki/Maintaining_a_WP7_and_WP8_version_of_a_same_Silverlight_application Good luck!
