I have a similar question. I have the 2011 ultra-pack and 2010 everything pack. Both are on separate hard drives that came with each package and both are upgrades. Can I install 2011 over the 2010 Hand Drive Version? The 2010 version contains some Norton styles and two fake books that I would like on my 2011. I plan on getting the upgrade for 2012 and would like to copy this version also. Since both are USP drives, I have been using them as stand-alones, one on my desktop and the other for my laptop. This would alow me to have a back-up of the latest and greatest in my collection.
