Opensearch service managed to opensearch serverless migration

Question

Hello everyone,

We are in the process of transitioning from a managed OpenSearch instance to a serverless setup on another AWS instance, and I have a few inquiries:

1. What are the recommended best practices for this migration?
2. I am unable to locate the "packages" tab in the serverless environment to define custom dictionaries. Could you provide guidance on this?
3. How can we determine the version of OpenSearch being used, as we need to ensure its compatibility with our Java client?

Thank you for your assistance.

Answer

Hello,

1. It is recommended to use OpenSearch Ingestion to migrate from a managed OpenSearch instance to a serverless setup but it is possible to use Logstash to migrate indexes. More information can be found here (https://docs.aws.amazon.com/opensearch-service/latest/developerguide/creating-opensearch-service-pipeline.html#pipeline-collection, https://aws.amazon.com/blogs/big-data/migrate-your-indexes-to-amazon-opensearch-serverless-with-logstash/)

2. Currently, custom packages are not supported in the serverless environment.

3. Serverless collection currently run OpenSearch version 2.0.x and as new versions are released, AOSS will automatically upgrade your collections to consume new features, bug fixes, and performance improvements.
