Upgrading from Vista to Windows 7 Pros: Unlike XP, Vista users do get a direct upgrade path to Windows 7, so your files and apps should migrate to Windows 7 without any problems. (You should
always backup before upgrading to be safe, and just to hedge your bets, you may also still want to
dual boot Vista and Windows 7 rather than installing Windows 7 over Vista.) Vista users will also get the cheaper upgrade price.
Cons: It probably won't affect most users, but the Vista-to-Windows-7 upgrade paths are actually limited by version in the following ways:
- Windows Vista Home Premium to Windows 7 Home Premium
- Windows Vista Business to Windows 7 Professional
- Windows Vista Ultimate to Windows 7 Ultimate
If you don't follow one of those three upgrade paths, you'll have to perform a fresh install
