    Utility lets you easily move your project from one server to another
    Утилита позволяет переносит базу любого проекта (Wordpress, Joomla, ModX, Textpattern, Concrete5, Contao) с одного сервера на другой, экспортируя её в виде .mysqldb файла.
    Если интересно, это чудо называется mysql_mover.
