Wazuh upgrades

Upgrading Wazuh central components and agents in the right order, with backups and cluster steps the documentation calls for.

Wazuh central components upgrade

Upgrading the Wazuh indexer, server and dashboard: component order, rolling indexer upgrades with shard allocation set to primaries, snapshots and backups, and validating alerts afterwards.

Wazuh agent upgrades

Upgrading thousands of Wazuh agents after the central components: remote upgrades with WPK packages, the API or agent_upgrade, local upgrades on each operating system and handling failures.

Wazuh 4.14 upgrade

Moving an older Wazuh 4.x deployment to the 4.14 line: what 4.14 adds, the patch release cadence since, and the checks to run on custom rules, decoders and dashboards after upgrading.
