title: Update/Upgrade Django 1.8 project code to Django 2.0
body: <p>I have a large django project built in 1.8 with about 14 apps and a large amount of dependencies.</p>
  
  <p>I already have a good idea about how I'm going to update the 2.7 code to 3.6 or possibly just make it compatible with both, however, I'm not sure what is the best practice and most efficient way to refactor/upgrade the django framework to 2.0 from 1.8. </p>
  
  <p>Bare in mind this thousands of lines of code so efficiency in terms of work is crucial.</p>
  
  <p>Thanks in advance for all suggestions!</p>
