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.
[Just like any other setting]({{site.url}}{{site.baseurl}}/install-and-configure/configuring-opensearch/), the alternative is to add the following line to `opensearch.yml` on each node and then restart the node:
Logstash OSS 8.0 introduces a breaking change where all plugins run in ECS compatibility mode by default. If you use a compatible [OSS client](#compatibility-matrices) you must override the default value to maintain legacy behavior:
You can download the OpenSearch output plugin for Logstash from [OpenSearch downloads](https://opensearch.org/downloads.html). The Logstash output plugin is compatible with OpenSearch and Elasticsearch OSS (7.10.2 or lower).
Some users report compatibility issues with ingest pipelines on these versions of Beats. If you use ingest pipelines with OpenSearch, consider using the 7.10.2 versions of Beats instead.
Beats versions newer than 7.12.x are not supported by OpenSearch. If you must update the Beats agent(s) in your environment to a newer version, you can work around the incompatibility by directing traffic from Beats to Logstash and using the Logstash Output plugin to ingest the data to OpenSearch.
The OpenSearch CLI command line interface (opensearch-cli) lets you manage your OpenSearch cluster from the command line and automate tasks. For more information about OpenSearch CLI, see [OpenSearch CLI]({{site.url}}{{site.baseurl}}/tools/cli/).
The OpenSearch Kubernetes Operator is an open-source Kubernetes operator that helps automate the deployment and provisioning of OpenSearch and OpenSearch Dashboards in a containerized environment. For information about how to use the operator, see [OpenSearch Kubernetes Operator]({{site.url}}{{site.baseurl}}/tools/k8s-operator/).
## OpenSearch upgrade, migration, and comparison tools
OpenSearch migration tools facilitate migrations to OpenSearch and upgrades to newer versions of OpenSearch. These can help you can set up a proof-of-concept environment locally using Docker containers or deploy to AWS using a one-click deployment script. This empowers you to fine-tune cluster configurations and manage workloads more effectively before migration.
For more information about OpenSearch migration tools, see the documentation in the [OpenSearch Migration GitHub repository](https://github.com/opensearch-project/opensearch-migrations/tree/capture-and-replay-v0.1.0).
