I want to move data from one Amazon OpenSearch Service domain to another. How can I do that?

Short description

You can use manual snapshots to migrate individual indices or entire OpenSearch Service domains. You can migrate data to a domain in the same account or to a domain in a different account.

Resolution

Before you begin, confirm the following:

You meet the manual snapshot prerequisites.
Your OpenSearch Service client is able to send signed HTTP requests to your domain’s endpoint.
The source domain is compatible with the Elasticsearch version of the destination domain. For more information, see Snapshot and restore on the Elasticsearch website.

Then, do the following:

1. Register the same manual snapshot repository on both the source and destination domains. Your destination is usually an Amazon Simple Storage Service (Amazon S3) bucket.

Note: You can use server-side encryption with Amazon S3-managed keys to encrypt the S3 bucket that you use as the snapshot repository.

2. (Optional) If you're migrating to another AWS account, attach a policy to the source S3 bucket that grants cross-account permissions to the destination.

3. Take a manual snapshot of the source domain.

4. Use the _restore API to restore the snapshot to the destination domain.

Amazon OpenSearch Service is the successor to Amazon Elasticsearch Service.
