Is this another scam? Got the following email ...

Question

Dear iTunes Customer,                  
Our records indicate that you have been using your AOL Username to sign in to iTunes Store, App Store or iBooks Store.                   
After the 30th March 2015, AOL will no longer support your ability to sign in to iTunes Store, App Store or iBooks Store. In order to continue using the store features, including the ability to access your previously purchased content, you must transition from signing in with your AOL Username to signing in with an Apple ID.                  
To make this transition, simply sign in once more with your AOL Username to iTunes on your Mac or PC. You will automatically be taken through a few short steps to complete the process.                   
When the process is complete, your new Apple ID will allow you to continue to purchase and download music, films, TV shows, apps, books and more. Additionally, your Apple ID will allow you to access other Apple services, such as iCloud and the Apple Online Store.                   
This transition does not affect any AOL services that you may be using with your AOL Username.                   
AOL Usernames which have not been transitioned to Apple ID will permanently lose access to iTunes Store, App Store and iBooks Store after the 30th March 2015. Apple will be unable to provide support for AOL Usernames which are not transitioned by this date.                   
To learn more about this transition, visit                    support.apple.com/kb/HT204268.                   
Regards,

This does appear to be a genuine message. The link goes to a valid Apple support document: Convert your AOL Username to an Apple ID - Apple Support
The text reads thus:
Convert your AOL Username to an Apple ID
Customers who use an AOL Username to sign in to the iTunes Store, App Store, or iBooks Store must convert to an Apple ID before March 31, 2015.
Starting March 31, 2015, AOL will no longer allow customers to use their AOL Username (also known as an AOL Screen Name) to sign in to the iTunes Store, App Store, or iBooks Store.
You must convert your AOL Username to an Apple ID in order to maintain access to the stores and to content you purchased previously.
Apple can't provide support for AOL Username accounts that aren't converted by this date. This transition doesn't affect any AOL services that you use with your AOL Username.
Convert your account
To convert your AOL Username to an Apple ID, sign in to iTunes on a Mac or PC with your AOL Username. Then follow the on-screen instructions.
Your new Apple ID will maintain your access to the iTunes Store, App Store, and iBooks Store, as well as all of the content you bought using your AOL Username. You can also use your Apple ID with iCloud and other Apple services.

(As above, but laid out a little differently)
If you currently sign in with an AOL screenname rather than some thing that look like a standard email address, <user>@<domain>, then presumably iTunes is going to walk you through the conversion process.
