How to change a Gmail Apple ID to iCloud.com ID?
Currently, I have two Apple IDs. One with the Gmail domain and another with icloud.com (Both active).
The Gmail one is my primary one and I have spent a lot of money from that account to purchase apps data etc... But now I want to change my Apple ID with my icloud.com email address. And when I tried to change it I received this error which I don't understand (Check Screenshot).
Another question is, after changing the ID, will I lose my purchases? I am changing my Primary/Gmail to icloud.com one.
Thanks for your help in advance.
