Apple One question about merging two Apple IDs
I use one Apple ID for the App Store and Music, and another for iCloud features and my Apple mail account. It seems it would be possible to port the iCloud etc. account to the one I use for Music and the App Store, but not the other way around. Correct? I'm a musician and have lots of my own recordings and other music I've loaded into Music as well as a large Apple Music collection and can't risk losing any of it. Of course, I also don't wish to lose all my apps, both Mac and iOS.....
