Apple is going you time to grieve your loss, though. If you’re really attached to your AOL ID, you have until March 31 to get a new scheme rolling. Past then, Apple says they “can't provide support for AOL Username accounts”.
All AOL sign-ins will need to be converted to an Apple ID. If you log-in using an AOL ID, you’ll be prompted to change, with instructions on how to go about it all.
We would urge you not to drag your heels, though. Apple says “AOL Usernames which have not been transitioned to Apple ID will permanently lose access to the iTunes Store, App Store, and iBooks Store after March 30, 2015.”
