how will that number look when you first autoconvert via 2to3?

I did two migrations of >500k loc projects in an afternoon each, and admittedly some days of testing to gain confidence since there where few unit test. But i found it to be very smooth sailing.

I was very familiar with both projects, so that helped a lot.

EDIT: I also want to add that i did this using python3.5, when to ecosystem seemed to be at a sweet spot of dependencies supporting both 2 and 3 mostly. I guess if one has been waiting until now, the divide between library versions will be a lot bigger.
