Change my iTunes id to my Apple ID.
I got my iTunes id way before an Apple ID. I no longer have access to that email account. It has been bought out by another company and discontinued. How do I change my iTunes id, with which I've purchased albums and movies, to be the same as my Apple ID? Mac Mini M1 2020, iPhone 13, iPad Pro 2021, MacBook Pro 2016
Mac mini 2018 or later
