Sell, give away, or trade in your iPad
Before you sell, give away, or trade in your iPad, see the Apple Support article What to do before you sell, give away, or trade in your iPhone or iPad, and be sure to perform the following tasks:
Back up iPad. If you replace one iPad with another, you can use the setup assistant to restore the backup to your new iPad.
If you’re replacing your iPad with another one you have on hand, you can use extra free storage in iCloud to move your apps and data from one iPad to another. Go to Settings
> General > Transfer or Reset iPad > Get Started, then follow the onscreen instructions.
Sign out of iCloud and the iTunes & App Store. Go to Settings > [your name], scroll down, tap Sign Out, enter your Apple Account password, then tap Turn Off.
Erase all content and settings that contain personal information. If you previously turned on Find My for your iPad, Activation Lock is removed when you erase iPad, making it ready for a new owner.
