I did modify some of the code to get the app to run on in IE10 on Windows 8. After modifying just a few lines of css the app started to run correctly.
After running my app through the simulator I got it to work on the Windows 8 App platform, and found it to be relativity simple converting apps to work with Windows 8.
I did have a certification issue where I had to change all my files to be UTF-8 encoded, but soon after I fixed the encoding I was able to port my app to Windows 8.
Thanks to all the commenters below.
