Re: Update django 1.8 project to 2.0 lts

I strongly recommend this approach:

My experience is that the best thing to do is to do minor upgrades - 1.8 -> 1.9.x -> 1.10.x -> 1.11.x (where x is the last patched version of each minor version).

Further, at the completion of one Django version, I recommend saving a snapshot of your database at that moment, and then starting the next upgrade in a new GIT branch :

Git branches:

mycode_django_1.8    #  Working version under 1.8

mycode_django_1.9    #  Working version under 1.9

mycode_django_1.10  #   ...

mycode_django_1.11  #   ...

Hi,

The reason for updating in this fashion, is that when you start the server on each version, you will get warnings about unsupported changes in the upcoming releases.

And of course - having a good test suite will be essential for upgrading successfully. 

When you have done the django upgrade, I would then do the python upgrade (just like others have suggested). Doing both at the same time will just become a huge task....

And of course - like others have also stated - django 1.11 is the LTS version, not 2.0. Upgrading to 2.0 is only necessary if you need the features that 2.0 includes (which is mainly changing to a different structure to the urls files and also deprecating python 2).

Good luck!

I have a large django project built in 1.8 with about 14 apps and a large amount of dependencies.

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.

Bare in mind this thousands of lines of code so efficiency in terms of work is crucial.

Thanks in advance for all suggestions!
