Hi, I tried to search, but no success. Now I'm running off my iCloud 50GB quota. My wife has 50GB plan too. We are both using iCloud Photo Library. I want to upgrade to 200GB plan and start sharing this quota to my wife and then stop paying her 50GB iCloud plan. What will happen with her iCloud Photo Library? Will it automatically "switch" to family shared space? Or should I download all her photos to her iPhone (she is using optimize storage option), then turn off iCloud Photo Library, downgrade her plan to free 5GB and after turn on iCloud Photo Library? Thanks for your answers.
