Upgrading from Django 1.3 to Django 1.5 shouldn't be a major problem, and
certainly shouldn't require a migration tool. There may be some minor
changes required in your templates (around the {% url %} tag), but
otherwise the code should run pretty much exactly the same. The error
you're describing is a problem with imports, and that *isn't* something
that has changed between Django versions.
In particular, your error message is talking about a module called
"simple". There's only one Django module with that name --
django.test.simple. To the best of my knowledge, that module didn't change
significantly between Django 1.3 and 1.5 -- certainly not in any way that
would result in an import error.
This suggests that the problem lies in either your own code, or in your
development environment. The fact that imports are now failing suggests
that it is the development environment that is the problem. Check all the
changes you've made that may affect import paths. If you're getting import
errors, open a Python shell and try to perform the import. If it doesn't
work at the shell, it won't work in a Django web server either.
Without any more details, it's near impossible to provide more help.
However, suffice to say that Django takes it's backwards compatibility very
seriously, and as long as you're using Django as documented, upgrading
between versions should not be a major problem.
