Historically, many multiple popular agents and ingestion tools have worked with Elasticsearch OSS, such as Beats, Logstash, Fluentd, FluentBit, and OpenTelemetry. OpenSearch aims to continue to support a broad set of agents and ingestion tools, but not all have been tested or have explicitly added OpenSearch compatibility.

As an intermediate compatibility solution, OpenSearch has a setting that instructs the cluster to return version 7.10.2 rather than its actual version.
Previously, an intermediate compatibility solution was available. OpenSearch had a setting that instructed the cluster to return version 7.10.2 rather than its actual version.

The override main response setting `compatibility.override_main_response_version` is deprecated from OpenSearch version 1.x and removed from OpenSearch 2.0.0. This setting is no longer supported for compatibility with legacy clients.

Most clients that work with Elasticsearch OSS 7.10.2 *should* work with OpenSearch, but the latest versions of those clients might include license or version checks that artificially break compatibility. This page includes recommendations around which versions of those clients to use for best compatibility with OpenSearch.

OpenSearch 2.0.0 no longer supports compatibility with legacy clients. Due to breaking changes with REST APIs, some features are not supported when using OpenSearch 1.x clients to connect to OpenSearch 2.0.
