freebsd-update for architecture migration?

[Eugene R]

Hi all!

I would like to suggest the the idea of extending the freebsd-update functionality to also handle architecture migration (the most evident use case is e.g. 9.3/i386 to 9.3/amd64 to support larger memory).

In my (uniformed) opinion almost all functionality should already be there (i.e. stage the replacement filetree, merge the configs and carefully copy over the live system) and the process should actually be even easier than major version upgrade on the same architecture (almost the same configs and layouts). The manual migration procedure basically does just that but it is rather manual, complicated and error-prone...

Does it makes sense?

Best wishes and Happy New Year!
