# UUID conversion

## Introduction

This was added in version 2.10. UUID conversion allows you to switch between different methods of UUID storage on your server.

### Offline - Mode

Will use the same UUID as an offline-mode server. The UUID will be based on the player name (case-sensitive).

### Lower - Mode

Offline mode but case-insensitive, as it gets the UUID from the lowercase username.

### Online - Mode

Use online-mode UUID provided by Mojang.

{% hint style="danger" %}
This mode will not work properly if you are using a pre-UUID version of Bukkit, or your server is set to offline mode. Please check your `server.properties` to be secure.
{% endhint %}

{% hint style="info" %}
If you use a proxy server (e.g. BungeeCord or Waterfall) follow this documentation to forward the player-UUID. Then the PlotSquared Online-UUID-Mode works also fine.
{% endhint %}

## Usage

A command is required to be executed in order to convert between methods of UUID storage.

{% hint style="danger" %}
You are strongly advised to backup your database before a conversion. Plots may be lost if something goes wrong!
{% endhint %}

`/plot uuidconvert <mode>`

## 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 following URL with the `ask` and `goal` query parameters:

```
GET https://intellectualsites.gitbook.io/plotsquared/features/uuid-conversion.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 `build a script that syncs our docs to a CMS` 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.
