Python Migration Error: TypeError: exceptions must be old-style classes or derived from BaseException, not str

I see. Thanks for the tips. If I run out of time I shall consider only using 2.5.

Yes.
Python 1.5 is very old. It's over 11 years old.
You might find it easier to first migrate to Python 2.5, where string 
exceptions are still legal and only generate a warning, and then migrate 
to 2.7.
Good luck!
