Install the new system fresh with the full x86-64 (AMD 64) distribution.
Then copy your data files over.  Thorough, faster, simpler, and you won't
run into weird application issues 3 months from now that require a week of
head scratching to figure out, only to realize that the problem is that you
never fully upgraded all the necessary stuff to 64 bit.
