question: Does an upgrade to OpenSearch require downtime? | ||
category: Upgrading | ||
category: Upgrading to OpenSearch | ||
--- | ||
You can perform rolling upgrades from Elasticsearch OSS to OpenSearch, which does not require downtime. Kibana OSS upgrades require a restart which will cause downtime for Kibana OSS and OpenSearch Dashboards. If you have a single-node deployment and wish to upgrade it in-place, you will incur downtime. |

There is no need to migrate secure or system indices for the upgrade to OpenSearch 1.0. This is because theses indices are not being renamed. In future upgrades, index aliases or migrations may be introduced for secure or system indices. |

All future OpenSearch 1.x releases will be backwards compatible with Elasticsearch 7.10. If functionality requires a breaking change, we will introduce a new major version of OpenSearch and provide tooling to make migrating to the new major version simple. When new features require adding APIs, we will work with the community to add support for these features in popular clients. |
