Can I put an app bought with an old ID on my iPad with its new ID? I bought the app for my old iPod Touch and used the second of two IDs I have...now I use another ID.  They're both mine.  I bought some apps with this alternative ID, can I put those apps on my new iPad?
Yes you can.


Open Settings.app
Scroll down and tap on "iTunes &amp; App Stores"
Tap on "Apple ID: [yourappleid@example.com]
Tap Sign out
After signing out of your "new" Apple ID sign in with your old one and download the app.
