When you upgrade Django with pip, you can install the latest version of 1.9 with `pip install --upgrade "Django>=1.8,<1.10"` and then the same for each version, until you want the latest version of 2.2 and then use "Django>=1.8,<3.0". (actually the 1.8 is not needed here, you can also use 2.2 etc.)
