I actually found an easier method here:
This works well. A couple of additional tips - you have to press "replace" many times - probably about 100! You also need to use Time Machine to restore your library files from the day before you upgraded to 11.
I am now back with 10.7, playing music with iTunes DJ.
I hope Apple fix 11 - there were some good features, but "NextUp" was not a replacement for iTunesDJ for me. I want to be able to see all details of upcoming music at a glance in the itunes full window.
