Is there another way to migrate from the professional edition to the home
edition besides formatting and re-installing the OS?
No. Downgrades aren't supported.
Why do you want to do this? Are you aware that the two editions are
identical except that Professional has some extra features not in
Home? There is *nothing* in Home that's not also in Professional, and
no advantage (except saving a tiny amount of disk space) to running
Home instead of Professional. Most people should stick with
Professional if that's what they have, and just never use those extra
features if they aren't desired.
