Re: Migrating older 1.4 project to 1.9

I have already suggested this approach to someone with a similar problem: upgrade one version at a time. I'm sure it is possible to find older versions; 1. upgrade to the next minor release (1.4 => 1.5, etc), 2. do the necessary adjustments, 3. goto 1.

It may be a lot of work, but at the end of the day you will have a perfectly upgraded application. I have successfully upgraded 3 apps this way, one of them being really big (tens of thousands of code lines).

Roger,

Yeah, I too have a large project that I'll hopefully be migrating
from 1.4 to 1.9 soon.

It's about 3.5 years worth of work, over 200,000 lines of code
in about 1000 Python source file and Django template files.

So any tips you come up with will be invaluable.  Please post
anything you learn to this thread.

Thanks!

I've inherited a moderately large project written 2 years ago using Django 1.4, and wondering if it is worth creating a fresh 1.9 project and porting in the old code, or doing an in-place upgrade to 1.9?

I have it running on 1.4 'as is' but if I run python manage.py migrate it comes unglued as a lot of stuff has changed since 1.4.
