Paris does not have native support for migrations, but some work has been done to integrate PHPMig. If you want to have migrations in your project then this is recommended route as Paris will never have migrations directly implemented in the core. Please refer to the Paris and Idiorm Philosophy for reasons why.

To integrate Paris with PHPMig you will need to follow their installation instructions and then configure it to use the Paris PDO instance:

$container['db'] = $container->share(function(){
    return ORM::get_db();
$container['phpmig.adapter'] = $container->share(function() use ($container) {
    return new Adapter\PDO\Sql($container['db'], 'migrations');
