From April 7, 2025 to April 14, 2025, Alibaba Cloud upgrades the deployment architecture of Alibaba Cloud Elasticsearch clusters and updates the SSL certificates of HTTPS listeners for the clusters. This topic describes the impacts of the upgrade and provides the upgrade schedule.
Impacts
After the deployment architecture of an Alibaba Cloud Elasticsearch cluster is upgraded, the system automatically restarts the Kibana node in the cluster. During the restart, the Kibana service provided by the cluster is unavailable for a short period of time. Other services provided by the cluster are not affected.
Precautions
Take note of the upgrade time of clusters in each region. During the upgrade, we recommend that you do not perform cluster update operations, such as cluster or node restart, cluster configuration upgrade, and cluster configuration downgrade, unless necessary.
