Migration in migration.

I read baout migrations, that looked in authManager. And I have a question about it…

I want create custom migration where I can (in php call)execute authManager migration. So I will looks like this one.




class ******_some_migration extends Migration

{

    public function up(){

        // some custom code

        $this->migrateUp('yii\rbac\migrations'); // this methods not exists

    }


    public function down(){

        // some custom code

        $this->migrateDown('yii\rbac\migrations'); // this methods not exists

    }

}

So I want to execute "yii\rbac\migrations" and add some custom code in one migration, how can I do this one?

WBR, thnx.
