The less patient Apple users among us may have long since abandoned their old third-party accounts and created an Apple ID using Apple’s own email addresses. That means you might have two Apple ID accounts. While Apple (still) won’t let you merge two accounts into one, you can use Apple’s Family Sharing feature to link your old account to your new one. Gather your old Apple ID information, follow Apple’s instructions for adding an Apple ID to your family group, and regain access to your old apps, music, and other media.
