How to overwrite controllers in FOSUserBundle?

Question

symfony

In general, a project fell into my hands, in which FOSUserBundle fell off after the update . Currently the versions are:

• FosUserBundle: "^2.1"
  
• Synfony: "2.8.*"
  

namespace UserBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class UserBundle extends Bundle
{
    public function getParent()
    {
        return 'FOSUserBundle';
    }
}
