# Acerca de la Extensión de compatibilidad con versiones anteriores

Este tema explica el propósito de la Extensión de compatibilidad con versiones anteriores y resume cómo implementarla en las tiendas.

Si está usando el Administrador Central basado en Flash, puede usar la **Extensión de Compatibilidad con versiones anteriores** para sincronizar datos entre el Administrador Central y una combinación de almacenes Flash y no Flash. Debe usar la Extensión de Compatibilidad con versiones anteriores si está actualizando gradualmente almacenes no Flash a Flash.

Para las tiendas sin Flash, debe instalar la Extensión de compatibilidad con versiones anteriores **en el mismo equipo** donde instaló tanto la aplicación del Servidor Central basada en Flash como la aplicación del Servidor Central no Flash.

Después de instalar la Extensión de Compatibilidad con versiones anteriores y la aplicación del Servidor Central, debe:

* Identificar qué almacenes son Flash y cuáles son no Flash.
* Apagar el servicio del procesador de hojas de cálculo en el equipo.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.rmhpos.com/es/installation/install-central-manager-multi-store/backward-compatibility/about-the-backward-compatibility-extension.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
