Correct. There has to be a conversion first before the rest of the
upgrade can complete.

I'm not actually a fan of such live updates via an applet anyway
personally. It's fine for technical people, but for non-technical folks
lots of things will break on their system until apps or the system is
restarted anyway. I quite like the offline updates stuff that is
happening in various corners for this kind of thing as it can all be
wrapped up into a neat little package for updating, but I digress. We'll
just have to find a nice way to bundle this up for mga[12].
