How can you change your Apple ID to a new email address?

Question

My old email was deleted and I used this as my Apple ID. I now have a new one and can't change my Apple ID on my phone and iPad, (Under 'icloud' in settings). However I have been able to change it in iTunes & App Store.
I also tried deleting the account and re doing it in my new one but it asks for the password due to find iPhone being on, and it won't do it. (I remember my old password)
Please help!
It's very frustrating and keeps wanting me to sign in.
Thanks

Answer 1

1) Did you change that old email address to your current email address to be your current Apple ID?  If so, try to enter your current password for your current Apple ID/iCloud account.  If it doesn't work, try #2.
2) If you don't have access to your old email account.  Same process, go to https://appleid.apple.com and sign in your current iCloud/Apple ID then edit it to your old email address then Save the changes.  DON'T sign out yet.  Go back to your iOS device then delete your iCloud account.  Once deleted, go back to the Apple ID website and rename it back to your current email address.  You have to verify it this time and you will be able to since you have access to that email address.
3) If your answer to #1 is NO, contact Apple Support (Account Security Team) to help you reset its password but you need to have another email address available which is not yet an Apple ID to send the password reset email.
Hope this helps!  Cheers!
