Important Notes
This upgrade will delete all persisted data of the Connectware broker. This includes client sessions, subscriptions, and retained data. If your configuration relies on any type of data persisted by the broker, make sure to properly initialize your applications after the upgrade.
If you rely on persisted data, create a backup or snapshot of the broker data volumes. This allows you to roll back in case of complications.
Upgrading Procedure
If your installation is older than 2.0.2, first complete the upgrade to 2.0.2 before upgrading to 2.0.5.
Delete the broker data volume of Connectware. For more information, see Deleting Broker Data Volumes on Docker Compose.
Download and install Connectware 2.0.5. For more information, see Upgrading Connectware (Docker).
