As you have a DLA award you cannot claim AA!
If you were under the age of 65 on 8 April 2013 (UK mainland), then notifying the DWP of a change of condition will result in your being invited to claim PIP.
If you were 65 or over on the above date, then you can ask to have your DLA reassessed, but you cannot receive an increased Mobility award if you currently have one, or any award of Mobility if you do not have a current award.
If you have further questions then please reply to this post and we will do our best to help.
