Earlier versions of Windows lack the architectural similarity to Windows 7. Consequently, there is no direct mechanism for an in-place upgrade or migration to Windows 7 from earlier Windows operating systems.

You cannot directly upgrade to Windows 7 from an operating system earlier than Windows Vista with Service Pack 1. Instead, you can perform a clean installation of Windows 7 on a computer that is running an earlier version of Windows and then migrate any user-related settings and user data. If your current operating system is earlier than Windows XP, such as Windows 2000 or Windows 98, you must migrate the user-related settings and data manually because neither USMT nor WET supports these earlier versions of Windows.
