4.2.1 -> 4.2+ upgrade

No major system service version changes.

4.0.0, 4.1.0, 4.1.1 -> v4.2.2 Upgrade

  • Elasticsearch will be upgraded from 5.6 to 7.2.

3.6.x -> 4.2+ upgrade

When upgrading a 3-Node appliance from 3.6.x to v4.2.2 the following services will be upgraded:

  • RabbitMQ upgrade to v3.7
  • Elasticsearch upgrade to v7.4

The upgrade process will not upgrade the external MySQL node(s). Refer to v4.2.2 Compatibility & Breaking Changes for externalized database version requirements.

Due to RabbitMQ going from 3.4 to 3.7, which has no rolling upgrade path, the RabbitMQ queues and configuration will be dropped, and the cluster will need to be configured and established again. This also ensures new queues are created using our new declaration settings, and removes any old queues not in use anymore.

Important

Due to the RabbitMQ upgrade from 3.4 to 3.7, the RabbitMQ configuration will be dropped and the cluster will need to be configured and established again.
