Migrate external OpenSearch or Elasticsearch snapshots to Aiven
Migrate an existing OpenSearch or Elasticsearch® snapshot to Aiven for OpenSearch® with minimal downtime and data integrity.
The migration process uses custom repositories and consists of the following phases:
- Configure a custom repository where your migrated data will reside.
- Migrate the data by restoring it from external snapshots stored on supported platforms like Amazon S3, Google Cloud Storage (GCS), Microsoft Azure, or other S3-compatible services.
- Optional: Reapply Index State Management (ISM) policies: Use a script to migrate ISM policies to maintain consistent index lifecycle management, including tasks like index rollover, retention, and deletion.
- Optional: Recreate security configuration: Use a script to migrate user roles, permissions, and access controls to preserve security settings and ensure a smooth user experience after migration.
