# Elasticsearch OSS Java high-level REST client
## Elasticsearch OSS Java high-level REST client
You may also continue to use the Elasticsearch OSS Java high-level REST client. Existing clients which have not yet migrated to using the OpenSearch Java high-level REST client should continue to work.
We recommend using the OpenSearch client to connect to OpenSearch clusters, but if you must use the Elasticsearch OSS Java high-level REST client, version 7.10.2 of the Elasticsearch OSS client also works with the 1.x versions of OpenSearch.
The 7.10.2 Elasticsearch OSS high-level REST client works with the 1.x versions of OpenSearch.
### Migrating to the OpenSearch Java high-level REST client
## Migrating to the OpenSearch Java high-level REST client
Migrating from the Elasticsearch OSS client to the OpenSearch high-level REST client is as simple as changing your Maven dependency to one that references [OpenSearch's dependency](#setup).
Migrating to the OpenSearch high-level REST client from the Elasticsearch OSS client is often a straightforward process of changing Maven groupIds and Java packages.
## Maven Dependencies
Change:
```
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.10.2</version>
</dependency>
```
to:
```
<dependency>
<groupId>org.opensearch.client</groupId>
<artifactId>opensearch-rest-high-level-client</artifactId>
<version>1.1.0</version>
</dependency>
```
## Java code
Once you have the OpenSearch client setup in your project, you should change existing Java package imports to `org.opensearch` from `org.elasticsearch`.
Afterward, change all references of `org.elasticsearch` to `org.opensearch`, and you're ready to start submitting requests to your OpenSearch cluster.
