It *may* work. It will probably work. It will, also, perhaps fail in
some points, but without telling you so.

The upgrade process takes care of a lot of things (see the source for
details). When you just switch repositories, all this care is thrown
out of the window. Most of the times it will still work. Except for some
details, like adjusting user preferences, paths, etc.

At least this is my experience, when I played with screwing up upgrades
(I was QA). YMMV.

Cheers,
