I am currently backing up my iCloud for my iPhone 6 to prepare to transfer over to my iPhone 11. Can I use my iPhone 11 now while the 6 is still backing up and then when it’s done, just upload all my iCloud storage on my iPhone 11 or do I need to wait completely until the backup is done to start using the 11?
iPhone 6s, iOS 13
If you add anything (e.g., photos) to the new phone before you use the data from the old phone to set it up, that data will be erased from the new phone and lost. The following may also help: Transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support
