Amazon OpenSearch Ingestion now allows you to migrate your data from Elasticsearch version 7.x clusters to the latest versions of Amazon OpenSearch Service managed clusters and both public and VPC serverless collections, eliminating the need for 3rd party tools like Logstash to migrate your data. This launch also enables you to migrate your data from 2.x version Amazon OpenSearch Service managed clusters to serverless collections. Additionally, you can now use Amazon OpenSearch Ingestion to replicate and migrate indexes between Amazon OpenSearch serverless collections.
