Copy photos from 1 iCloud account to another
My wife has gotten her Apple IDs all in a twist and she now has three different Apple ID accounts, each with different content. Of course, Apple does not let you merge accounts.
We've decided which one to use going forward and dealt with music, app purchases, etc. already.
The one thing left is photos and messages. She has 3,864 photos in Account X, and about 9,800 more in Account Y.
- Account X photos are stored in her iPhone and in Account X's iCloud account
- Account Y photos are stored in her iCloud account, and are also in the Photos app on her Mac, which is set to use iCloud Photo Library and is now also set to download originals to the mac (it's processing a 32GB upload/download sync right now)
We will be using only Account Y for all iTunes and Apple store logins going forward. I just need to get all the photos from the phone where she is logged into account X, and ensure they all inside account Y.
On the phone (iPhone 8), if I go to Settings and try to logout of account X, it warns me all the photos will be deleted from the device. Was hoping I could simply log out from X on the phone, log in from Y, and hoping iOS would then upload all the photos, messages, etc. that are on the device into account Y. But if it's going to delete them from the device at logout, it seems that wouldn't work.
What is the easiest way for me to get all the photos from one iCloud account to another? I tried downloading AnyTrans, a 3rd party product, but it wouldn't install -- generic error.
