Wazuh version upgrade from 4.2.7 to a latest version

[Shenal Perera]

Hi Team,

We have an old Wazuh version running in our environment and are planning for an upgrade.

As this is a very old version, could you let us know which upgrade path to follow?

1 - Can we directly upgrade to the latest 4.14 version?

2 - We have Windows agents installed on several devices. Should these agents also be upgraded to the latest version?

3 - Are there any other key areas that I should be aware of?

Thank you

Hi Shenal

Please allow me some time; I’m currently looking into this and will get back to you with an update as soon as possible.

Hi Shenal,

I have replicated this on my end and successfully upgraded it to the latest version.

To upgrade to Wazuh 4.2.7, you should follow the official migration process for both OpenDistro/OpenSearch components and Kibana/Wazuh Dashboard.

I recommend following this sequence: Indexer → Manager → Filebeat → Dashboard, as this ensures a smooth upgrade flow.

Start with the Wazuh Indexer migration guide:
https://documentation.wazuh.com/4.3/migration-guide/wazuh-indexer.html

Follow the steps up to step 5. In step 6, instead of installing a fixed version of the indexer, you can install the package without specifying a version so it upgrades to the latest available release, for example:

apt-get -y install wazuh-indexer

Then continue with the remaining steps up to step 18.

After that, proceed with upgrading the Wazuh Manager and Filebeat by following the upgrade guide:
https://documentation.wazuh.com/current/upgrade-guide/upgrading-central-components.html#upgrading-the-wazuh-server

Since you are upgrading from an earlier version, you may need to update your ossec.conf, especially for:

• ruleset configuration blocks

• vulnerability detection settings

• indexer connector configuration

You can refer to the shared documentation section to apply the correct updates.

Continue the process through Filebeat installation and configuration as described.

Finally, follow the Wazuh Dashboard migration guide (not the general upgrade guide):
https://documentation.wazuh.com/4.3/migration-guide/wazuh-dashboard.html

In step 3, make sure to run:

apt-get -y install wazuh-dashboard

Otherwise, an older version may be installed by default and follow the rest of the steps to complete the configuration.

Let me know if you face any issues during the process, and I’ll be happy to help further.
