Microsoft Spells Out Terms For Windows XP, 2000 Users Upgrading To Vista
A page on the Microsoft Web site outlines which users will have to install Vista from a clean hard disk, and who can just install it over existing software.
Microsoft has posted a page to its Windows Vista site that sorts out upgrade options for users of Windows 2000 and Windows XP.
"Certain legacy OSes require a full system installation while others will allow for an in-place upgrade," said Vista program manager Nick White on the team's blog. "Depending on where you're coming from and where you're going, you should determine which scenario applies to you."
According to the chart, only Windows XP Home, XP Professional, XP Media Center, and XP Tablet PC users will be able to upgrade in-place, and then only to specific versions of Vista. Windows XP Professional, for example, will be able to do an in-place install only to Vista Business and Vista Ultimate. To upgrade to Vista Home Basic or Vista Home Premium, a Windows XP Pro user would first have to back up all files; after adding Vista, he would need to reinstall all applications and restore the saved data files.
Microsoft also noted that anyone using a Windows prior to 2000 can only upgrade to Vista with a clean install and using a full copy of the operating system, as opposed to an upgrade edition.
