Add upgrade documentation for Kubernetes from 4.2 to 4.3 Wazuh indexer migration #314
Description
Hello team,
Since Kubernetes has grown in popularity as a deployment method, we should consider having upgrade guides for Wazuh migration.
For example:
From Wazuh 4.2.x to 4.3.x, the Kubernetes manifest as well as the docker images had breaking changes that involves multiple steps before doing an upgrade. The migration to the new Wazuh environment (Indexer) should be explained too.
In situations like this, we should have an upgrade guide/migration guide with the steps to perform those upgrades.
Regards,
Miguel
