This moving an installed 32-bit system to 64-bit has so much potential for food shooting, that I don't think we should come close to making it easy. There is reason that no other Unix supports such a thing on AMD64. People should back up their data and do a fresh install. Those that are true hard-core tinkers, a recipe has been posted. If they don't understand the steps and can't follow them; they probably shouldn't be trying this approach. -- -- David (obrien@FreeBSD.org)
