Someone told me today that he'd like me to do an ecommerce application for him, the project is huge so I told him that it would take months or a year. He was fine with that but asked me if I could deploy a simple ecommerce website for him meanwhile.
There are many options out there but I told him I'd pick Wordpress, it's simple and he's fine with it. Upon completion of the application I'm hired to write, is it simple to migrate, data and user accounts to my application assuming I use Mysql/mariadb? Of course the database scheme will be different.
