Prerequisites for Upgrading to Elasticsearch Version 6.8.6
Prerequisites for Upgrading to Elasticsearch Version 6.8.6
Before you upgrade to Elasticsearch version 6.8.6, you must ensure that your existing Elasticsearch version 6.2.3 contains the following properties in the
elasticsearch.yml
file:
cluster.name:<user defined value>
node.name:<user defined value>
You must migrate these properties from your existing Elasticsearch version 6.2.3 configuration directory to the Elasticsearch 6.8.6 configuration directory. Execute the migration steps in the exact order listed.
If your existing Elasticsearch version 6.2.3 does not contain these configuration properties, do not upgrade to Elasticsearch version 6.8.6 as your existing Elasticsearch version is not compatible.
