I'm about to dive into that myself, as my rigs are going to fall out of support in April, but I haven't yet. I do know that PW works differently, despite trying to emulate both, and so the old methods and configurations don't necessarily work.
I suspect I'll end up rebuilding those rigs from scratch, but I've documented them well enough that it should be okay. Forget the old mentality, and come at this with fresh eyes and PW's own documentation.
At any rate, I'm following this thread now. :-)
