Unfortunately we dropped the support for the Intranet starter kit because it had many issues and wasn't very useful. You can try to upgrade it to 4.4, just like any other Sitefinity project, but officially it is not supported and we cannot guarantee that it will be working flawlessly. We suggest that you try other samples like the updated Education Starter Kit.
