Porting to new Python version

[Gabor Urban]

Hi,

I have a tough issue: we are using a Python application written quite
a time ago for version 2.4. The code is mature, and there are no bugs.
 My bosses came up with the idea to port it to the latest release... I
am not really convinced that it's a good step.

I wellcome any information pro and contra. I would like to get the
background as precisely as possible.

Thanks in advance and good day to You!
