The easiest way to update is to make a backup of your data and then
reinstall the amd64 version.

Yes, that would be best. Make a list of all installed ports (e.g. with
portmaster -L), delete all ports and install the so-called root ports
(No dependencies, not depended on) and leaf ports (have dependencies,
not depended on) again.

It is possible, but I've never bothered trying it.
