Amazon OpenSearch Service now supports rollback for service software updates
Amazon OpenSearch Service now supports rollback for service software updates, giving you greater control when managing updates to your Amazon OpenSearch Service domains. Previously, once a software update was applied, there was no self-service option to revert it to a previous version if you encountered an unexpected issue.
Software update rollback uses a blue/green deployment. You can initiate a rollback within 15 days of a service software update being applied, using the new RollbackServiceSoftwareUpdate API, the AWS CLI, or the Amazon OpenSearch Service console.
Rollback option for service software updates is now available in all AWS Regions where Amazon OpenSearch Service is available. To learn more about the software updates and rollback option, refer to the Amazon OpenSearch Service documentation.
