# Update to 3.0

This page describes what you need to do in order to upgrade to MyPet 3.0

### Step 1 - Put the new JAR file in place

If you are running [MyPet-NPC](/mypet-3/hooks/npc.md) too you can delete that now as it is included into MyPet itself.

### Step 2 - Convert the skilltrees

{% hint style="info" %}
**If you never touched the skilltrees you can skip this step!**
{% endhint %}

If you made your own skilltrees or edited the default ones you need to convert them to the new format using the following steps:

1. open up the new SkilltreeCreator
2. select the folder you want to save your new skilltrees in
3. your browser will open and you will see the new [Skilltree Creator](/mypet-3/systems/skilltrees/skilltreecreator.md)
4. open the menu on the top left hand corner
5. select `Import Legacy Skilltree`
6. follow the 3 steps of the wizard
7. hit the save button
8. upload the new `.st.json` files to the **skilltrees** folder on your server

### Step 3 - Adjust your config files

MyPet doesn't support numeric item IDs anymore. All settings that requires an [config item](/mypet-3/setup/configurations/configitems.md) will require the 1.13 item ID even if you don't run a 1.13 server

## 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://wiki.mypet-plugin.com/mypet-3/setup/update-to-3.0.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.
