I'd like to change Cluster External IP Address but CVM IP Address is NOT change.
Do I have to stop the cluster ? or Do I change that online?

You can change that in either CLI or GUI , You dont need to stop your cluster but this will result in failure if any services configured with Cluster Virtual ip Address,
Example: If you have configured remote cluster with Cluster Virtual ip address then changing this ip result in error then you will have to go and enter the new ip to establish the connectivity
