You should get Platinum APs.
I did this just recently with some old vouchers from 2011 or so. I had read here on the DIS that we should be issued Disney Platinum Passes. I was confused at first because the physical passes we were handed were gold in color so I asked the CM to verify that the passes have no black out dates and that photo pass is included and she confirmed that that is what we got. I later looked up my tickets in
MDE and they are listed as platinum passes.
Be prepared to spend a looooong time at the ticket window when you exchange your vouchers. The CM we got was very confused about what to do with vouchers that old and had to call someone to come over to the ticket booth to help out. It took at least 20 minutes to get our passes.
