CHANGING a few WORDPRESS METAKEYS

Hello, I run an ecommerce marketplace on wordpress. I started off with Dokan theme ( [login to view URL] ) and going to switch over to [login to view URL] THIS MUST BE DONE TODAY, YOU CAN NOT GET OFF LINE AND MUST STAY IN CONSTANT CONTACT. PLEASE DO A GOOD JOB AND MAKE SURE EVERYTHING WORKS. This requires some custom database php scripts and superior knowledge of mySQL . You must keep a change log in English. METAKEY: dokan_profile_settings VALUE:a:10:{s:10:"store_name";s:9:"blueyes44";s:6:"social";a:5:{s:2:"fb";b:0;s:5:"gplus";b:0;s:7:"twitter";b:0;s:8:"linkedin";b:0;s:7:"youtube";b:0;}s:7:"payment";a:1:{s:6:"paypal";a:1:{s:5:"email";s:20:"PAYPALEMAIL";}}s:5:"phone";s:0:"";s:10:"show_email";s:2:"no";s:7:"address";N;s:8:"location";N;s:12:"find_address";N;s:6:"banner";s:5:"15362";s:8:"gravatar";s:5:"15355";} I want to extract the store name and paypal email. Map these to the new metakeys: PayPal Email --> eddc_user_paypal Store Name --> name_of_store
