This has probably been discussed a thousand times before, but with all the crazy vb3 talk I'm having a hard time lately filtering out the good stuff.

Is there a thread or document on the methods used for converting over a hack?

I have a custom made hack that a guy built for me. Very small, but unique and necessary to my site. At the very least I want to start playing around to find what it will take on my part to get it to work with vb3 (even in beta)

I'm assuming there are a few major change necessary to each hack, then probably minor things to watch for (db changes, etc.)

Could someone point me in that general direction? Much appreciated.
