When you install using the 64 bit CD don't select the default settings
when it shows you the existing systems installed, choose the advanced
option that takes you to page where you can specify which partitions
to install onto, and choose the one that currently contains the 32 bit
version (if there is anything on the 32 bit version that you need to
keep then back it up first).  That will replace the 32 bit version
with the 64 bit one.

However note that some (including myself) have decided to stick with
the 32 bit version even on 64 bit hardware.  There is some performance
advantage with 64 bit but it seems that there are also still a few
problems, notably with regard to flash.  I am going to wait a little
longer before moving to 64 bit.  Others will no doubt suggest that 64
bit is fine.  It is up to you.

Also as others have noted it is essential to back up all important
data (including on the XP system).  Things can go wrong when messing
about with partitions.  Of course all your important data is well
backed up anyway. :)
