Change world seed in Minecraft Java Edition

Attention

Create a backup of your server beforehand, as the current world can be lost by changing the world seed.

Open your dashboard and select your Minecraft Java Edition server.
Go to the file browser.
Open the file server.properties.
Look for the following entry:
```
level-seed=
```
```
level-seed=
```
Insert the desired world seed at this point (e.g. level-seed=5101553622029575588).
save the file and restart the server for the new world seed to take effect.

Tip

You can find out the current world seed of an existing world by entering the command /seed in the game.
