ApsaraDB for Redis allows you to change the endpoints or port numbers of ApsaraDB for Redis instances. You can change the port number of an instance to improve security. You can also change the endpoint of a new instance to the endpoint of the original instance without the need to reconfigure your application.


The instance that you want to manage is in the Running state.


After you change the endpoint or port number of an instance, you must update the connection information on your client. This way, the client can connect to the instance by using the new endpoint or port number.
