Elasticsearch:Upgrade a cluster

Last Updated:Aug 19, 2026

As your business grows, you may need higher cluster specifications. If the current configuration cannot handle your workload, you can upgrade the cluster. This topic describes how to upgrade an Alibaba Cloud Logstash cluster and what to consider beforehand.

Considerations

Upgrading a cluster triggers a restart. The restart duration depends on factors such as the cluster specifications, data structure, and data volume. Perform this operation during off-peak hours to minimize the impact on your services.

Procedure

  1. Sign in to the Elasticsearch console.
  2. In the top navigation bar, select a region.
  3. In the left-side navigation pane, click Logstash Clusters, and then click the target cluster in the list.
  4. On the Basic Information page, click Upgrade in the upper-right corner.
  5. On the DataWorks Exclusive Resources (Subscription) page, in the Change Specifications section, click Edit under Logstash Nodes.
    Note Alternatively, on the Logstash Clusters page, find the target cluster, and in the Actions column, choose More > Upgrade Configuration to open the cluster's DataWorks Exclusive Resources (Subscription) page.
  6. In the expanded node configuration, modify parameters such as Category, Disk Type, Storage Space per Node, and Data Nodes.
    For parameter details, see Create an Alibaba Cloud Logstash cluster.

    The Current Configurations section shows your cluster's current configuration.

  7. Select the Agreement of Service checkbox and click DataWorks Exclusive Resources (Subscription).
    After you complete the purchase, the cluster restarts. The upgrade is complete once the restart is successful.
