The simplest way to do 32-bit to 64-bit upgrade would be to backup your data, install from scratch, then restore data; mixing 32-bit and 64-bit stuff together, especially without 32-bit stuff moved to the right place, is among the most terrible mess you wanted to avoid. Online "upgrade" can be done if you have your 64-bit world/kernel built and installed into a separate directory (i.e. make world kernel DESTDIR=/path/to/a/temp/place), then drop into single user mode, then tar then pipe to another tar to extract the whole thing to /, but this is really a "foot, gun, shoot" thing.
