The method outlined in the docs is correct -

What I can add to the above answers is the rationale. If you're very far behind in Django versions (ex. 1.5 -> and you want to go to 2.0) the developers only want you to upgrade one step at a time. ex. 1.5 -> 1.6 -> 1.7 etc.
The purpose being that this limits the amount of things that break on upgrading. You should include the -Wa
warning flags every time you upgrade a step, so you can fix deprecated features before they are removed in future upgrades.
A feature is generally deprecated for a couple of versions, and then removed entirely. So this gives you the ability to keep the app stable while upgrading.
