My 8 yr old iPad has older system and 16GB about used up. Rather than clean out unused apps, I opted for the latest on sale at Amazon, 9.7, 32GB. Before it arrives, I have to decide what to do with the old one that has my sheet music, MP3s etc. What I have on it works fine, and am tempted to leave it alone and start with some newer music apps on the new. or transfer some.

I don't want to waste the new capacity with redundant data, but wonder if having two will cause confusion with iTunes when it comes to uploading material. What have some of you done?
