Old Apple ID deleted, itunes music being held hostage
I have a dilemma - my old desktop Mac is holding my music library (mostly CDs I loaded into iTunes back in the day) hostage because the account (a mac.com account) no longer exists. My husband says that our mac.com account was moved to an icloud.com account and Apple help desk says since the mac.com account no longer exists, my music, including my own, is no longer accessible.
Can this be true? Is there anyway to move that library over to my newer Macbook without access to that deleted account? Help please.
MacBook Pro 13″, macOS 10.15
