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:

  1. Configure a custom repository where your migrated data will reside.
  2. 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.
  3. 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.
  4. 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.
