You don't need to rebuild, although there are known problems with having 
both 4.7 and 4.8 installed, and having 4.7 be the active one (or any 
case where an older version is the active one.)

You should be able to just switch to 4.8 without rebuilding anything. 
That's what I did. Of course it can't hurt to rebuild everything, but 
you can schedule that for later (like an overnight rebuild of @world 
with --keep-going). It's not critical to do it immediately.
