Microsoft has unveiled a
Vista upgrade matrix, detailing which present versions of Windows are eligible for upgrading to one of the four relevant versions of Vista (Starter and Enterprise are targeted for specific markets and therefore not included in this matrix). To make matters a bit complicated, however, some editions (such as XP Pro or Win2K) are only eligible to upgrade to a "corresponding or better" version of Vista, i.e. - Business or Ultimate. As icing on the cake, some ugprades will require a fresh wipe and install, while others can be upgraded 'in-place', retaining your applications and settings.
To be clear, however: all present versions of Windows listed in this chart are eligible to purchase
upgrade editions of Windows Vista. Previous versions, such as Win98 and ME, will have to purchase a full edition of Vista.
