Switching from a family iCloud account to a personal.
So currently I'm in a 2 TB family plan and we have been using 1.8 TB out of it. My own iPhone has been using almost half of it.. For example my photos itself has about 700 GB. I need to leave the family plan and get my own space.
As far as I know, in order to not lose any data before leaving the family plan, I need to download all the data (original photos etc) to my phone. The problem is my phone has 256 GB storage only. Therefore, it will be impossible to download the data to my phone ..
So I'm looking for the best and the safest way to switch the iCloud+ accounts without losing any data.
The only thing comes to mind is backing up everything to a computer or an external hdd and after getting the new iCloud plan, I will upload from the back up. Is that possible? Am I missing anything? I just want to be very cautious before doing anything wrong.
Thanks in advance for your help
