# 从现有版本迁移

{% hint style="danger" %}
重要的是要确保你进行一次 [一致性备份](/on-premises/zh-cn/wei-hu/data-and-backups.md#performing-a-consistent-backup) **之前** 每次重大版本迁移，以便在需要时可以回滚。
{% endhint %}

如果你使用的是官方 overleaf 工具包，只需添加一个名为 `docker-compose.override.yml` 并将以下或类似内容添加到 `overleaf-toolkit/config` 目录：

{% code title="docker-compose.override.yml" %}

```yml
---
服务：
    sharelatex：
        镜像：ghcr.io/ayaka-notes/overleaf-pro:latest # 或 X.x.x
```

{% endcode %}

要启动你的实例，请运行：

```
bin/up
```

就是这样！你已经全部就绪。

## 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://ayakaleaf-pro.ayaka.space/on-premises/zh-cn/an-zhuang/cong-xian-you-ban-ben-qian-yi.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.
