Migrate from Elasticsearch to Aiven for OpenSearch® with Migration Assistant on Google Cloud

Migrate Elasticsearch or OpenSearch workloads to Aiven for OpenSearch® on Google Cloud Platform (GCP) using the open-source OpenSearch Migration Assistant.

The OpenSearch Migration Assistant is an open-source, Kubernetes-native tool that handles migrating to OpenSearch. It covers metadata migration, index mapping, live traffic capture and replay, and comparison tooling to validate your target cluster before cutover.

For full deployment and configuration instructions, including GCP-specific setup, see the Migration Assistant documentation.

Configure Aiven for OpenSearch as the target cluster

1. Create an Aiven for OpenSearch service if you do not already have one.

2. In the Aiven Console, open your service and go to the Overview tab. Note the following connection details:

   • Host
   • Port
   • User (default: avnadmin)
   • Password

3. In your Migration Assistant workflow configuration, set the target cluster endpoint and credentials to these values.
