Well, I gave up...the only thing (I could find) was being able to transfer the ratings on songs. So, I don't think you can load a new zune with the exact same content loaded to your old one. If there is a way that I've missed, I hope someone will share that info here so others will know how!
I can see that I can look at the song list within the music area and go back and forth between the settings for the old zune and new one and update from the old settings, but it will take quite a while that way.
It would be nice to have a way to transfer your settings automatically for those of us upgrading our Zune.
