# v1.4.3 Migration Guide

***

## Antes

Anteriormente, los usuarios tenían que crear 2 flujos para realizar upsert y consultas:

### Upsert

### Cargar Existente

Con esta técnica, hay 2 desventajas:

* Se necesita hacer una llamada adicional al LLM para que ocurra el upsert
* Cualquier cambio pequeño causará que el flujo se vuelva a insertar

## Después

Ahora, el usuario puede usar un solo nodo para lograr todo:

Los usuarios ahora tienen la opción de iniciar manualmente el upsert haciendo clic en el botón **verde** en la parte superior derecha:

Viene con la nueva API - `/api/v1/vector/upsert`:

En el futuro, implementaremos funciones para consultar y eliminar índices. Este es el primer paso hacia una forma más flexible de realizar operaciones relacionadas con vectores. Recomendamos encarecidamente a los usuarios que actualicen a los nuevos nodos.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flowiseai.com/espanol/documentacion-oficial/migration-guide/v1.4.3-migration-guide.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
