Hello, Without know the details of your project it's impossible to give you a definite answer. It will depend in part on how much of the code base uses GeoTools classes, and how complex that use is. However, I certainly wouldn't recommend trying to do an incremental port through successive versions because I'm sure that would involve a lot of redundant doing and undoing of code.
Version 2.4 is before my time (or at least beyond my memory) but one thing to keep in mind is that although there have been many changes between then and now, there has also been a lot of improvement and simplification, not to mention better docs and examples. If it's a large project, perhaps the best thing to do is to break it up into conceptual or functional chunks and then post questions about how best to implement each of these.
