Upgrading Ubuntu from 12.04 to 14.04

[Uri Even-Chen]

Hi people,

I work at my job with Ubuntu 12.04 and we run Django 1.4.12 locally with
Python 2.7.3 and PostgreSQL. We want to upgrade Django from 1.4 to 1.6 and
I also thought it would be a good idea to upgrade Python to 2.7.6 and maybe
even 3, so I tried to upgrade Ubuntu to 14.04. But after I completed the
upgrade, Django didn't work and I couldn't even run migrations (with
South). I had to reinstall Ubuntu 12.04 and I lost all the files I had in
my home directory (because I chose not to keep Ubuntu 14.04) except some
files that I backed up. My questions are:

1. What do we need to do in order for Django to work with Ubuntu 14.04?
2. Why isn't it possible to reinstall Ubuntu 12.04 after upgrading to 14.04
and still keep all the files in my home directory, while not keeping all
the other files (the operating system files)?

Thanks,
Uri Even-Chen
