# Kompatibilität und Updates des Mandantenmaklers

Wenn Sie Parallels RAS auf eine neuere Version aktualisieren, gelten die folgenden Regeln für die mandantenfähige RAS-Architektur:

* Parallels RAS Mandantenmakler unterstützt Mandanten, die bis zu zwei Haupt-RAS-Versionen älter sind. Wenn Sie z. B. ein Upgrade von RAS Mandantenmakler von RAS 17 auf RAS 18 (oder die nächste Hauptversion, sobald diese verfügbar ist) durchführen, werden Makler mit Parallels RAS 17 unterstützt.
* Wenn Sie Updates durchführen, sollten Sie zuerst den Mandantenmakler aktualisieren, damit Ihre mandantenfähige RAS-Installation voll funktionsfähig bleibt. Sie können Mandanten später während ihres eigenen Wartungsfensters aktualisieren.

## 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.parallels.com/landing/ras-admin-guide/v21-de-de/mandantenfaehige-architektur-des-ras/kompatibilitaet-und-updates-des-mandantenmaklers.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.
