icloud storage
My wife and I both purchased our own iCloud storage (200GB) separately. She is now running out of storage space while I still have plenty. I found from the forum that we could not combine our storage purchase as a "family share". How do we make the transition to have one of us purchase 2TB and shared by both? What's the process of smoothly transitioning without interrupting or losing all our photos on the Cloud? Thanks
