Can I Change the Security Group of a CSS Cluster?

Constraints

• It is advisable to perform this operation during off-peak hours.
• The security group cannot be changed for clusters created before February 2023. To do that, create a new cluster by selecting the desired security group, then perform Migrating Data Between Huawei Cloud Elasticsearch Clusters Using Backup and Restoration to migrate its data to that new cluster.
• Make sure the inbound rules of the new security group allow all the ports required for service access. For Elasticsearch and OpenSearch clusters, port 9200 must be allowed. For Logstash clusters, port 9600 must be allowed.
