Apple Music Student Plan
I linked my student email to a Apple ID and use it for my Apple Music Student plan.
Now I have got a new Apple ID, how do I subscribe with a student discount using my new Apple ID instead of the old one?
Question marked as
An Apple ID is just an email address. An Apple account is the entire package with password and its own set of files and services associated with that account. (Unfortunately people consider them synonymous but they are very different things.) So what did you get a new one of? An email address, or an account? The best thing to do if all you did was get a different address is to change the address used with the account that already has the subscription.
Here's how you change the email address you use for your Apple ID:
1. Go to https://appleid.apple.com and sign in.
2. In the Sign-In and Security section, choose Apple ID.
3. Enter the email address that you want to use as your Apple ID.
4. Choose Change Apple ID.
5. If you changed your Apple ID to a third-party email address, check your email for a verification code, then enter the code. Learn what to do if you didn't get the email. --> If you didn't receive your verification or reset email - Apple Support
6. If you use services like iCloud or Messages to share with friends and colleagues, sign in to those services with your updated Apple ID. --> What to do after you change your Apple ID or password - Apple Support
