I suggest bringing the Django code only as far as 1.11 in Python 2.7.
Django 1.11 is a LTS version.

Then I would advance the same code to Python 3.x and get that working as
a separate ring-fenced project. You can do that away from production or
using six and other dual-Python tricks you can also deploy 3.x code to
production. I have been writing in 3.x and deploying in 2.7 for quite
some time. One of these days I'll switch the production server to
Python3 and drop 2.7.

Only with Django 1.11 and Python 3.x working properly in production will
I advance to the next Django 2.x LTS version

Oh, and heaps of tests :)
