Is there any particular reason you don't want to upgrade? For my projects, it's usually just an uninstall of the old package, and a re-install of the new package, and I'm back in business. Very few things break between SDK versions.
Although the time to un-install and re-install is way too long. Sometimes I start a re-install before I walk the dog or something, just to avoid having to wait for the computer.
