In order to transfer an iOS application, the buyer will first need to create a Developer account with Apple. Once both parties have a Developer account, send your Apple ID and your Company or Team Number to the seller.
Only the Team Agent for the seller’s account can initiate an app transfer. From the App Summary page, click on the Transfer button and fill in the buyer’s information. The buyer will receive an email prompting them to accept the transfer.
For more information on transferring applications, see the Transferring and Deleting Apps section in the iTunes Connect Developer Guide.
