What's the best way to upgrade Django?

Question

Django

Good day.
I have a project on Djano-Oscar(1.1)(Django 1.8), I want to upgrade its version. How can I do it better? Immediately to the latest version, or gradually over feature releases (1.8 -> 1.9 -> ... )?
And in general there are any recommendations, reefs? As I understand it, first you need to upgrade Django, and only then Django-Oscar?
Thanks in advance for your help.

If you have a normal project and at least 60-80% of tests are covered, then you just apache versions of everything - you run the tests, see what is broken. You fix it. You repeat until it works.
