I have two ipads with different apps on them.
  There are a few old apps in my old ipad that I want to put on my new ipad that aren't in the app store any longer.
  They are in my itunes storage, but when I try and drag and drop them into my new ipad screen to sync them
  it asks me are you sure you want to remove 57 apps from your ipad.
  I have 381 of apps in itunes library and I don't feel like searching through them all and checking them off to do a total sync.
  Is there a way to just simply add one app?
  thank you
