-This playbook is an end-to-end runbook for migrating an existing [Amazon OpenSearch Service](https://aws.amazon.com/opensearch-service) domain to an [Amazon OpenSearch Serverless](https://aws.amazon.com/opensearch-service/features/serverless) collection, using a vector-search workload as the worked example. For a small domain — a handful of vector indexes totaling a few tens of gigabytes — plan for roughly 90 minutes end to end, most of which is unattended snapshot and backfill time.

-This is a backfill-style migration: Reindex-from-Snapshot (RFS) takes a point-in-time snapshot of the source domain, migrates metadata, and bulk-indexes documents into the collection. Amazon OpenSearch Serverless does not accept snapshot restores, ISM/ILM policies, ingest pipelines, custom plugins, or `_cluster/settings` changes, so the runbook below builds the collection’s shape with security policies and metadata migration rather than a restore. For the broader conceptual comparison, see [Migrate to Amazon OpenSearch Serverless](./migrate-to-serverless.html).

-Amazon OpenSearch Serverless authenticates every request with AWS Signature Version 4 (SigV4) — there is no basic-auth or fine-grained access control (FGAC) username and password on the target. Both the snapshot source access and the migration’s write access to the collection are governed by [AWS Identity and Access Management](https://aws.amazon.com/iam) (IAM) and by the collection’s data access policy.
