Editing an MQTT Connection Alias
You might need to edit an MQTT connection alias. For example, you might want to change the alias so that subscribers do not use a clean session. Or, you might want to change an MQTT alias so that the MQTT server no longer sends a last will message on behalf of Integration Server when Integration Server disconnects abruptly.
Keep the following information in mind when you edit an MQTT connection alias.
You must disable an MQTT connection alias before you can edit it.
The MQTT connection alias name cannot be edited.
Changing the
Connection Client ID may result in new subscriptions on the MQTT server for MQTT triggers that use the alias. The subscriptions that use the old connection client ID are not automatically removed from the MQTT server. Old subscriptions might contain messages and continue to receive messages.
