The question itself hints that you're using stuff that isn't stable, and 
even more so, changed significantly between 1.0 and 1.5.

I know that there was a migration guide some sort, not sure if that was

Anyway, if you're using things we don't consider APIs (because we may 
not have APIs there, or because we didn't go through doing that), you'd 
hardly find docs, let alone docs that say how to migrate from one to the 

To some extent that is what you get from living in an open dynamic
