I'm stuck with a specific requirement on my magento shop. I have enabled the guest checkout method on magento to remove the necessity of registering.
But now this information is useless for providing customized experience to the customer in future if he registers himself. When the person who has used guest checkout previously, registers himself on my shop, I want his previous orders to get attached with his account, so that his whole shopping history can be combined to give him better shopping experience. Is there any possibility to do that within the possibilities of magento. If any of you have done that previously, please give any pointers to achieve this. Please, feel free to provide other better alternatives, if my thoughts are wrong somewhere. I'll greatly appreciate any help, thanks in advance.
Edit: I got success in editing customer's name and other options, but still looking for some help to attach the customer's account to the order, so that it is available in the order history of customer.
