As someone who's taken over a similar project in the past, I'm going to give you a piece of advice you're not going to want to hear. Do it by hand. Do not use a tool to do your work.
As if that isn't enough, you're probably going to also need a whole bunch of documentation. I'll bet you don't have most of the following:
Those documents are at least as important than the code, because they tell you what the code is supposed to do. The code just tells you what it currently does. Are you sure that what it does right now is correct? How much are you willing to bet?
Furthermore, most tools aren't able to use many of the reasons to use Perl in the first place. For example, I doubt a tool could reasonably handle
I hope you really choose to do this by hand. It will take about 3-6 man-months to do it. (I'm not kidding - it won't take that long.)
The idea is a little like C++ templates, except not quite so brain-meltingly complicated. -- TheDamian, Exegesis 6
