My wife and I swapped iPads.
She had an iPad 2. I had an iPad mini. Same hardware, different sizes. I didn’t use the mini much because it was too small to enjoy some of the work (and play) I enjoy. She used the larger iPad constantly, but found it hard to tote around. Now, she has the portability that helps her and I have the larger size that I craved.
We should have done it a long time ago.
iCloud backup and restore
Swapping was a cinch.
We both manually initiated a backup to iCloud before we erased and deleted the contents of each iPad. This reset them to act as if they were brand new. “Hello. Welcome to iPad.” All that remained was logging into our respective iCloud accounts, plugging in the devices, and waiting for everything to download.
The exchange took about two hours to complete, though they were only rendered unusable for about 15 minutes during the delete and reset. The experience was nearly flawless. Now, she can easily carry the iPad mini in her purse and I can happily write in Ulysses for iPad.
