 _<sup>1</sup> The Index Lookup tool replaces the three deprecated legacy index tools: Vector Index Lookup, Vector DB Lookup, and Faiss Index Lookup. If you have a flow that contains one of those tools, follow the [migration steps](./index-lookup-tool.md#how-to-migrate-from-legacy-tools-to-the-index-lookup-tool) to upgrade your flow._
