From April 1 to April 15, 2026, Alibaba Cloud Elasticsearch will perform a deployment upgrade and renew HTTPS certificates for clusters. Review the schedule and impact for your region.
Impact
During the upgrade, Kibana nodes will restart, causing a brief Kibana service disruption. Core Elasticsearch cluster services are not affected.
Notes
Check the deployment upgrade schedule for your region. Avoid configuration changes—such as cluster or node restarts and scaling operations—during the upgrade window unless an emergency requires them.
