That’s not porting from 32bit to 64, that’s just running your 32bit code on a 64bit machine to make sure it still works.
The way to do that is to just test all the functionality on the 64-bit machine, just as you do every time you release a new version, right? 🙂
If you really want to port it (i.e., compile it to a 64bit executable), the first step is to just try it. You may find it works as-is. I’d only be worried about porting problems if you try it and then problems appear.
Then, and only then, would I go looking for the causes. Otherwise it’s potentially wasted effort.
