Speaking as someone who took a Python 2 codebase (moosic) that was being
dropped with the move to Python 3, and updated it to work with Python 3,
without having been more than can-read-it-well-enough familiar with
Python before that point:

It's entirely doable, but the degree of difficulty and amount of work
will depend on the specific codebase involved.

In my case, I started with the last Debian package version before the
removal, imported the source package into git, dropped the debian/
directory because that doesn't belong in the upstream codebase, ran the
'2to3' tool (from the package of the same name) against the codebase,
committed the result, and started doing "build" / run tests of the
updated code (including comparisons back and forth with the untouched
Python 2 version of the codebase).

Lots of things didn't work at first, but it only took me a day or so to
get it working far enough for a few of the program's features to be
functional, and another day or two to get the rest into shape. I've
since taken over as upstream maintainer, am working to get the package
back into Debian (although it's currently low project priority), and
have done a bit of work adding features and fixing bugs into the bargain.

The details in your case might be significantly different, but I assure
you that it *can* be done, it's just a matter of how opaque the codebase
is, and how many manual changes need to be made after what the 2to3
conversion tool does.
