Upgrading Elasticsearch

Starting with release 9.0.002.80, Web Services and Applications require Elasticsearch 7.8. No data migration from the previous version is needed.

Important
You need to deploy Elasticsearch 7.8 in parallel with the existing Elasticsearch 6.x and update the elasticsearch.yml file.

The following options must be set in the elasticsearch.yml file on each Elasticsearch node:

  • action.auto_create_index: false
  • bootstrap.memory_lock: true
  • thread_pool.write.queue_size: -1
Tip
The ELASTICSEARCH_ADDR parameter in the /opt/genesys/gws/kubernetes/parameters.yaml file has to point the new Elasticsearch 7.8 installation.

After a successful upgrade of Web Services and Applications you can remove Elasticsearch 6.x.
