I recently went from 1.11 -> 2.0 -> 2.1 -> 2.2 over the course of about a week, deploying to production each time we had all test passing to ensure there wasn't anything amiss. There were actually relatively few changes to get there, the upgrade to Python 3 was a bigger (albeit still manageable) change. I'm expecting very few changes to get onto Django 3.0, will probably wait till the first bug fix release though as it tends to catch a few things. The best thing to go is run the dev server with `python -Wd` to get the depreciation warnings, and fix them before each upgrade. Worked perfectly!
