In order to import my Microsoft Money 2007 data into Quicken 2007, I had to install Quicken 2005 first, import the Money 2007 data using the Data Converter, then start Quicken 2005 to finish the importing process, uninstall Quicken 2005, install Quicken 2007, then upgrade, and... finally done! It was a tedious process. But it works. Not everybody wants to jump through that many hoops though. At the end, though, I stayed with Money (due to Quicken's stability issues).
