Do you have a list of dependencies that are causing you the issues? When I did my migration (about 9 months ago) I found that there were a few dependencies that had been superseded by much better libraries. At the time there were a couple where I had to use a py3 branch, but no longer.

One of the most annoying ones is Thrift. But I just googled it and it seems like they are very close to supporting Python 3. A couple others - mysql-python, fabric, oauth2. These are the ones that are on the wall-of-shame. But I didn't test the entire dependency set.

I think on the mysql front there are a few alternatives (I use postgres now - and if there was any way of going that route, I'd do that instead). I believe the pure python version is the popular choice these days [0].

I mentioned it because when I went through the process, I was looking for py3 support from my existing libraries and didn't consider swapping them out (as in, initially it didn't even occur to me).

In some cases I found far better libs that were more actively developed (eg I ended up using xlsxwriter for my excel stuff and it was way better than my previous solution).

ps I believe they like to call it "Wall of Superpowers" these days :)
