Upgrading Connectware to 1.7.0 (Docker)

How to upgrade Connectware to version 1.7.0 on Docker.

Connectware 1.7.0 affects the backward compatibility of the Connectware broker. Older broker data volumes are not compatible with brokers of Connectware 1.7.0 and newer. Upgrading to Connectware 1.7.0 requires additional upgrade procedures.

Additionally, multi-factor authentication (MFA) is now controlled via a dedicated configuration switch.

Check your upgrade path

This upgrade is one step of a longer upgrade path. Before you continue, check Connectware Upgrade Paths to determine which steps apply to your installation.

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

1. To stop Connectware, go to the Connectware installation directory (default: /opt/connectware) and run docker compose down.

2. Delete the broker data volume of Connectware. Find the broker data volume in the list of volumes with docker volume ls and delete it with docker volume rm <connectware_brokerData>.

3. If you are using multi-factor authentication (MFA), set the environment variable CYBUS_MFA_ENABLED to true inside your .env file.

4. Download and install the new Connectware version. For more information, see Upgrading Connectware (Docker).
