My AOL address is my Apple ID - why am I being told to change it?
My AOL address is my Apple ID and I have been receiving emails that look very suspicious (a few of them I've found in my spam folder) that tell me I need to change my AOL Apple ID by end of March 2015. I now see it appears to be legit since there is a page on the Apple site about it. So I changed my Apple ID to my gmail address. Is that all I have to do? I don't want to lose access to all my purchases made with my AOL Apple ID. This is really confusing and the documentation Apple has provided regarding this is very unclear.
