There have been detailed instructions on the amd64 list how to go from i386 to amd64 "the hard way", i.e. via the sources, but that's not the officially supported way, as far as I know. Simply re-installing from an ISO is faster and less error-prone. You'll have some downtime either way anyway. If you need to minimize downtime, it's probably a good idea to install on a separate HD, and switch HDs when you're ready. That approach also has the nice advantage that you have a very easy fall-back in case something goes wrong: simply switch to the first HD again. Of course, YMMV.
