# Di chuyển từ hệ thống hiện có

{% hint style="danger" %}
Điều quan trọng là đảm bảo rằng bạn thực hiện một [bản sao lưu nhất quán](/on-premises/vi/bao-tri/data-and-backups.md#performing-a-consistent-backup) **trước khi** mỗi lần nâng cấp phiên bản lớn để bạn có thể quay lui nếu cần.
{% endhint %}

Nếu bạn đang sử dụng bộ công cụ Overleaf chính thức, chỉ cần thêm một tệp có tên `docker-compose.override.yml` với nội dung sau hoặc tương tự vào `overleaf-toolkit/config` thư mục:

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

```yml
---
services:
    sharelatex:
        image: ghcr.io/ayaka-notes/overleaf-pro:latest # hoặc X.x.x
```

{% endcode %}

Để khởi động phiên bản của bạn, hãy chạy:

```
bin/up
```

Vậy là xong! Bạn đã sẵn sàng.

## 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/vi/cai-dat/di-chuyen-tu-he-thong-hien-co.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.
