# 旧バージョンの RAS からのアップグレード

RAS v16.x を実行する既存のファームをテナントとしてテナントブローカーに接続するには、以下の手順を実行します。

1. ファームを RAS 17.1 以降にアップグレードします。
2. ファームをテナントとしてテナントブローカーに接続する方法については、[**「テナントブローカーとテナントの展開」**](https://download.parallels.com/ras/v19/docs/ja_JP/Parallels-RAS-19-Administrators-Guide/45470.htm)[セクション](https://download.parallels.com/ras/v19/docs/ja_JP/Parallels-RAS-19-Administrators-Guide/45470.htm)を参照してください。
3. ローカル接続のためにローカルの RAS Secure Gateway を使用する計画がなければ、ファームの接続後に削除して構いません。その他の情報については、[**「実装の概要」**](https://download.parallels.com/ras/v19/docs/ja_JP/Parallels-RAS-19-Administrators-Guide/45438.htm)を参照してください。

# 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.parallels.com/landing/ras-admin-guide/v21-ja-jp/ras-nomaruchitenantokitekucha/bjonno-ras-karanoappugurdo.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.
