NIS/NAV 2007 Licenses for NIS/NAV 2010

Hi.  I have a couple of unused (never activated) licenses for NIS 2007 and NAV 2007 that I would like to use on new computers that I am about to build.  I am wondering if, like NIS 2009, my 2007 licenses will still work on the 2010 versions.  If yes, would I be able to download the 2010 versions on my computer directly and activate the licenses from there without needing to install the 2007 versions first, and then upgrading to 2010 afterwards?  Any info would be appreciated.  Thanks.
