.. warning::

Downgrading to version 4.11 and earlier is not possible. Since version 4.12.0, Wazuh uses a newer version of Apache Lucene.

Apache Lucene does not support downgrades, meaning once you upgrade to Wazuh 4.12.0 or later, you cannot roll back to 4.11 and earlier versions without a fresh installation of the indexer.

To avoid data loss, create an :ref:`index snapshot <migrating_indices_take_snapshots>` before upgrading. For more details, refer to the `Opensearch documentation <https://opensearch.org/docs/latest/install-and-configure/upgrade-opensearch/rolling-upgrade/#:~:text=Important%3A%20OpenSearch%20nodes%20cannot%20be,before%20beginning%20the%20upgrade%20procedure.>`__.
