In Symfony 4

public function somename(ObjectManager $om, TokenStorageInterface $ts)
    {
        $user = $this->getUser();
        if ($user) {
            $user->setRoles(['ROLE_VIP']); //change/update role
            // persist if need
            $om->flush();
            $ts->setToken(
                new PostAuthenticationGuardToken($user, 'main', $user->getRoles())
            );
            //...
        } else {
            //...
        }
    }
