Upgrading ElasticsearchΒΆ

Liferay supports Elasticsearch 7. The compatibility matrix provides the latest support details.

Important

Solr integration is deprecated as of Liferay 7.3 and removed in 7.4, replaced by Elasticsearch integration. Migrating to Elasticsearch requires setting up Elasticsearch and connecting Liferay to it.

Important

Elasticsearch 6.x is not supported on Liferay 7.3+.

Before planning your upgrade, read Upgrading Search Infrastructure. It provides an overview of the steps required to upgrade older Liferay/Elasticsearch systems to the latest supported search stack. Always back up your search indexes before upgrading Elasticsearch.
