Apple ID change consequences
I want to change Apple ID to a new email but I wonder what will happen to my @icloud.com email account. Will it still be active?
Let's say my current Apple ID is ABC@gmail.com and I'm using ABC@icloud.com, I want to change Apple ID to 123@yahoo.com. Will ABC@icloud.com still be active after the change?
I also know for sure that 123@icloud.com is not available, already in use by somebody else, would it be a problem somehow?
Thank you in advance for any help 😃
