You mean CSS classes generated by RichFaces? Not unless someone makes one I'm afraid, I assume there's a good number of those that have no equivalent since the layout may have changed, though those that we have should simply be shortened names of the original ones, e.g. "rich-tree-node-icon" -> "rf-trn-ico", granted it's still nothing you can run through Find+Replace.
Oh, that's bad news ...
I hope one of the RF team creates such a list in the migration guide for the next major version update (or better ... keep things backward compatible).
Thanks for the reply anyway.
