In case you are using any custom plugin then you will need to use the HiveMQ 4 extension framework to rebuild it.

The HiveMQ 4 extension framework gives you the ability to seamlessly augment HiveMQ broker functionality with custom business logic. Use the framework to integrate HiveMQ with virtually any external system. The superior extensibility of HiveMQ ensures that your MQTT broker is able to deliver the right fit for your particular environment. For more details please check our documentation.
