I am planning to replace my existing computer which runs WindowsXP Home
Edition and buy a new computer that runs Windows Vista Home Premium. On my
existing computer I have Microsoft Office XP Standard (Version 2002). One
of my questions is whether my Office XP can be moved to the Windows Vista
computer; e.g. by uninstalling from my old computer and reinstalling on the
new computer. Does anyone know whether this is possible? And, if not, do I
have to outright buy the new Office 2007 for Vista?

FYI, my Office XP is a standalone version that I bought retail (not
preinstalled on the old computer) and I have the original Office XP disc.

Thanks.
