Force sync photos across 2 iPhones with same iCloud account
Hi folks, long story short I got a new phone 15 but got locked out of my iCloud account for the 5 day waiting period. While it was locked out I did use the new phone for a bunch of photos. Once unlocked both my new phone and old phone are logged into iCloud with the same account. I want to transfer the old phone to the new phone now but I don't want to lose the photos taken with the new phone when it gets wiped.
How can I force sync the photos from the new phone to the old phone for my iPhone transfer? Again both phones are logged in with the same iCloud account. Thank you!
iPhone 14 Plus, iOS 16
