Amazon OpenSearch Service now supports one-click migration from legacy OpenSearch Dashboards to OpenSearch UI, for both OpenSearch domains and serverless collections. OpenSearch UI is the new, zero-downtime, serverless interface for search and unified observability across multiple data sources. With this launch, the multiple tenants and thousands of saved objects you created in legacy OpenSearch Dashboards become reusable in your OpenSearch UI applications, reducing the operational complexity of moving between interfaces.
