well i would recommend save the list of packages you have and don't format 
your /home partition, then start with new x86_64 else it's weird i think.
I did it that way and works fine(hey installing arch works in 15 minutes 
doesn't it? ;) ).
You could also save your existing 686 as a chroot if you have the space to 
safe it.
