How to perform a minor upgrade
Example: Wazuh 4.9 → Wazuh 4.11.
The workload's versions are pinned in the charms.
No automatic upgrades will happen if they're not triggered at the charm level.
Wazuh server
The Wazuh server has a stateless workload. It can safely be upgraded through juju refresh.
While the workload is stateless, some data are temporarily stored on disk before being sent
to Wazuh indexer. So you should not destroy or recreate the application and/or the units.
Wazuh dashboards
The Wazuh dashboards charm has a stateless workload. It can safely be upgraded through juju refresh.
Wazuh indexer
This is where all data are persisted so upgrades should be done carefully.
The recommendation is to follow the Upgrade guide from the OpenSearch charm documentation.
