How to merge two/more customers account in magento

Question

Is it possible to merge two or more (copying customers orders and other stuff ) customer accounts?

is it possible in magento?

Answer 1

There is no such backend functionality, but it must be possible by editing the database directly. I have never done this, so don't use this in a productive system, but I would propose you do:

• choose one of the customers that you wnt to keep, and get its entity_id from the customer table
• get the entity_id of the second customer, and replace it with the first entity_id in the address-tables, order-tables, wishlist- and quote-tables and (maybe) some more
• delete the second customer

I am typing this free, so I don't know the actual table names atm. Do you need a list, or can you find them yourself?

    $keepid = $keepcustomer->getId();
    $keepemail = $keepcustomer->getEmail();
    $keepegroup = $keepcustomer->getGroupid();

    foreach($mergeids as $id) {

        $customer = Mage::getModel('customer/customer')->load($id);

        $email = $customer->getEmail();

        $orderCollection = Mage::getModel('sales/order')->getCollection()
                           ->addFieldToFilter('customer_email',$email);


        foreach($orderCollection as $order) {

            $order->setCustomer_id($keepid);
            $order->setCustomer_email($keepemail);
            $order->setCustomer_group_id($keepegroup);
            $order->save(); 
        }

        // $wishList = Mage::getSingleton('wishlist/wishlist')->loadByCustomer($customer);
           $wcollection = Mage::getSingleton('wishlist/wishlist')->getCollection()
                            ->addFieldToFilter('customer_id', array('eq'=>$id));

           if ( count($wcollection)>0 ) {
               foreach($wcollection as $wish) {
                   $wish->setCustomer_id($keepid); 
                   $wish->save();
