You will have to use this method to restore back to MJ5 - http://forum.xda-developers.com/show....php?t=2559715
And then you will have 2 OTA's to install. First is a minor update, and the second is Kitkat (NC2).
If you update to NC2 (Kitkat) via OTA it will lock your bootloader down more. You will not be able to restore back to MJ5, and as of right now there is no root available.
