Sometimes, a clean slate is exactly what a server needs. Whether you want to generate a new seed for a fresh season or just reset the Nether for a new update, here is how you do it safely.

Before You Start: Back It Up!

Resetting a world is permanent. Before you delete anything, we highly recommend creating a Snapshot in the Backups tab. If you change your mind later, you'll be glad you did.

How to Reset Your Entire World

To get a completely fresh map with a new seed:

Stop your server in Mission Control. (This is important! If the server is running, it will just recreate the files you delete).
Go to the Files tab.
Find the folder named world (or whatever you named your world in server.properties).
Select the folder and hit Delete.
Start your server. Minecraft will notice the world is missing and generate a brand-new one automatically.

How to Reset Specific Dimensions

Maybe you love your overworld base, but your Nether is a mess. You can reset just the Nether or the End without touching your main world.

Stop your server.
Open the Files tab.
Look for these specific folders:
- The Nether: Delete the folder named world_nether (or DIM-1 inside your world folder).
- The End: Delete the folder named world_the_end (or DIM1 inside your world folder).
Start your server. New versions of those dimensions will be generated the next time someone enters a portal.

Changing Your Seed

If you want a specific new map, follow these steps before starting the server back up:

Go to the Settings tab and open the World sub-tab.
Find the line that starts with level-seed=.
Type in your new seed after the equals sign.
Save the file and then start your server.

Note: If you are running a modded server (like Forge or Fabric), you might see different folder names like world/dimensions. If you're unsure, feel free to ask for help on our Discord!
