I have just installed RC build 7137 on top of RC build 7000 using the "upgrade" rather than the "clean install" option (or without needing to use any of the stuff in the "here" link in YupYup's post above) and I am happy to report that it went through with no problems at all. My settings and programs all came through the upgrade unscathed -- with one minor firewall issue on my ESET Internet Security program, which I am workingto resolve.
So, in my opinion, don't bother with a clean install to move from one RC to the next: choose the upgrade option!
