Did some checking.
Vista x64 -> Vista x64 upgrade is possible and legitimate. Beta2 -> RC1
upgrade is also supported. Upgrade to RC1 over other beta builds is not
supported (but is not disabled and will probably work, judging from the
posts of people who have tried it). You can upgrade XP SP2 (x86) to Vista
RC1, or Vista Beta 2 to RC1 (either x86 or x64, naturally, you cannot use
the upgrade to switch platforms).
Microsoft also recommends that you install all of the critical updates for
Vista Beta 2 before you upgrade. These are available through the Windows
Update control panel.
