Migrate django1.2 project to django1.4
Python does not support backward compatibility,consider that you may get some issues on migrating to 2.7 from 2.4.
We developed project with django version 1.2 and python 2.4. Now we want to migrate the projects into latest version (Django1.4 and python2.7).
I am very new for migration, Can anyone please advise on this. 
What things do I need to take careof?
Do we need to rewrite all the code again?
