Regarding copying or cloning vector index tables, it appears that direct copying or cloning is not possible, as Databricks throws the message: "Securable with kind TABLE_ONLINE_VECTOR_INDEX_REPLICA does not support Lakehouse Federation."
It seems that vector index tables cannot be copied or cloned directly and must be recreated or synchronized from a Delta table. Does anyone have more information on whether it is possible to directly copy or clone vector index tables?

Direct cloning of a vector index table may not be possible. However, if Databricks generates the embeddings, you can enable "Sync computed embeddings" to save them to a Unity Catalog table. Alternatively, you can set the parameter sync_computed_embeddings=True when creating the vector index using the Python SDK for Vector Search to store the generated embeddings in a writeback table, which can then be cloned.
