Thanks in advance
You can define your controller as service, then get it in another controller.
In your services.yml define needed controller as a service:
services:
service_name:
class: BundleName\Controller\YourControllerName
Then in any controller you'll be able to get this service via container:
$otherController = $this->get('service_name');
$otherController->methodName();
