# Configuration V2

This section of the documentation describes the YDB clusters configuration method called V2, which is the experimental way to configure YDB clusters version v25.1 and above.

<!-- source: en/devops/configuration-management/_includes/experimental_v2.md -->
{% note warning %}

This article is dedicated to YDB clusters that use [configuration V2](https://ydb.tech/docs/en/devops/configuration-management/configuration-v2/index.md?version=v25.3). This configuration method is currently experimental and is only available for YDB versions starting from v25.1. For production use, we recommend choosing [configuration V1](https://ydb.tech/docs/en/devops/configuration-management/index.md?version=v25.3) — it is the main method and is officially supported for all YDB clusters.
