Hi Mike-
I think the gist of your question has been answered a couple of times in the top thread (Andrew's) - see below, although there were a smattering of similar questions/answers:
Not sure how clear this will be: (sorry my iPad won't let me copy the link):

So would I be able to use the Pro-Channel FX that I currently have in X3 Pro in the new Sonar if I only had the new Professional version? What about Dimension Pro and Rapture Full and things like Breverb Sonar VST, PK-64, VX-64, TL-64, etc. ? Or will it give me a message that these plugins don't work with this version of Sonar? I don't really every use most of these, but I'm curious for anyone else who would like to know. It certainly makes the Professional version seem like a good deal/value.
Also curious if the Vocal Sync is a plugin or if it's an integrated feature that is simply "grayed out" in the Professional version?
If you go to Professional you won't lose any of those plugins or ProChannel modules. I'll have to check but I do believe POW-r is only in Platinum. So going to Professional is an option. VocalSync is integrated right inside SONAR. That's actually one of the cool things vs. something like Vocalign. It previews real-time and you can open it right in the track view and adjust. Check out the video. It's not greyed out in Professional because it's not there.
