How to change the world seed of your Minecraft server.
Changing the seed on your Minecraft server is easy. Every Minecraft world is made using a seed, which is like a secret code that helps create mountains, forests, and rivers.
Finding the seed
You can use the "/seed" command in-game. You'll need to be an operator for this to work.
Changing the seed
Head over to the Game Panel and select "File Manager" on the sidebar menu.
Click on the server.properties file to edit it.
Change the level-seed value to your new world seed.
Once done, click "Save File" and restart your server to use the new seed.
