Amazon OpenSearch Service adds a new connection mode for cross-cluster connection, simplifying the setup required to remote reindex between a local domain and remote VPC domains. Remote reindex enables you to migrate data from a source domain to a target domain. Remote reindex is also useful when you have to upgrade your clusters across multiple major versions. 

Previously, to use remote reindex, you needed to confirm that the source domain was accessible from the target domain. If the remote domain was VPC enabled, you set up a publicly accessible reverse proxy for the remote domain, even when the domains were located within the same VPC. 

With this release, you can create a new connection between a local domain and a remote VPC domain using the connection mode ‘VPC endpoint’, and then use the provided endpoint in the remote reindex operation. You do not need a proxy, and the traffic between domains remains within the Amazon Networking Backbone--at no extra cost. The new connection mode is available for local domains running OpenSearch versions 1.3 and above. To learn more about the new connection mode and how to use it for remote reindex please refer to the documentation.

The new connection mode for cross-cluster connection is now available in the AWS Regions where Amazon OpenSearch Service is available, with the exception of AWS GovCloud (US) and Asia Pacific (Melbourne). Please refer to the AWS Region Table for more information about Amazon OpenSearch Service availability.
