How do I migrate data from one OpenSearch Service domain to another?
I want to move data from one Amazon OpenSearch Service domain to another.
Resolution
Use manual snapshots to migrate individual indices or entire OpenSearch Service domains. Migrate data to a domain in the same AWS account or to a domain in a different account.
Note: You can also use manual snapshots to back up individual indices or the entire domain.
Prerequisites:
- You meet the manual snapshot prerequisites.
- Your OpenSearch Service client can 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.
Complete the following steps:
- 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 (SSE-S3) to encrypt the S3 bucket that you use as the snapshot repository. - (Optional) If you're migrating to another account, then attach a policy to the source S3 bucket that grants cross-account permissions to the destination.
- Take a manual snapshot of the source domain.
- Use the _restore API to restore the snapshot to the destination domain.
