# How to Change Your Minecraft Server Version

Change your server version to access new features or maintain compatibility with players.

## Changing the Version

1. Stop your server and [create a backup](/panel/backups)
2. Go to the **Startup** tab and change the `Version` field
3. Go to the **Settings** tab and click **Reinstall**
4. Start your server and run `/version` to verify

<Warning>Downgrading is difficult and can corrupt worlds. Always backup first and check for incompatible blocks.</Warning>

### Java Version Requirements

If you get a Java error, change the `Java Version` in the **Settings** tab:

* **Java 8**: Minecraft 1.14 - 1.16.5
* **Java 16**: Minecraft 1.17 - 1.17.1
* **Java 17**: Minecraft 1.18+ (Recommended)
* **Java 18-21**: Latest versions

## Common Issues
