[Answer]-Upgrade python 2 to 3 and django 1.6 to 1.7

Like the comment says, use unit tests and make sure every single line of your code is hit by your tests. A lot of the module names have changed/were moved or combined with other modules. Every time your unit test says it cant find a certain module or method you can use this guide to figure out how to rename your imports/function calls.
