Merging an old Bioware Social Network account with my current Origin one.

I have an origin account from [edit: email address removed] which also has most of my achievements and my dlc from Dragon Age but I also have my very old Bioware Social Network account [edit: email address removed] with older exclusive DLC items and I need to merge the two for use with the Dragon Age Keep for the upcoming Inquisition game. I need to move all my DLC from my old BSN ([edit: email address removed]) to my current Origin linked one ([edit: email address removed]) for ease of access and for the Keep. I can verify my identity for both of them. Thank you for your time.
