Minecraft servers allow you to replace the current world, create a new world while keeping the existing one, or completely reset your world and start fresh. This guide covers each option and explains how to change the seed used when generating a new world.

​
Create a New World Without Removing the Existing One

If you want to try a new world but may want to return to your current one later, you can change the world name in your server configuration.
  1. Log in to the game panel at gamepanel.fourseasonshosting.com.
  2. Stop your server from the Console page.
  3. Go to Files and open server.properties.
  4. Locate the level-name= setting.
  5. Change the value to a new world name. For example:
  6. Save the configuration.
  7. Start the server.
Since a world with that name does not exist yet, Minecraft will create a new one automatically. Your previous world will remain in the server’s files. To return to it, simply change level-name back to the name of the original world and restart the server.

​
Completely Reset the World

If you want to permanently start over with a newly generated world, you can remove the existing world folder. Before deleting anything, create a backup if the existing world contains anything you may want to keep.
  1. Stop the server from the Console page.
  2. Open the Files section.
  3. Locate the world folder currently being used. Its name should match the value configured under level-name in server.properties. In many installations, this is world.
  4. Select the world folder and delete it.
  5. Deleted files are moved to the Trash, allowing you to recover them if necessary.
  6. Start the server.
Minecraft will detect that the configured world no longer exists and generate a fresh world.

​
Modded Servers

Depending on the modpack or server setup, additional dimension folders may also need to be removed when performing a complete reset. Examples include:
  • world_nether
  • world_the_end
Check your specific modpack before deleting additional folders, as some modded servers handle dimensions differently.

​
Generate a World With a Specific Seed

The world seed controls how Minecraft generates the terrain and structures in a newly created world. Changing the seed will not alter an existing world. To use a custom seed:
  1. Stop your server.
  2. Open Files and edit server.properties.
  3. Find the level-seed= setting.
  4. Enter the seed you want to use. Leave the value blank if you want Minecraft to choose a random seed.
  5. Save the file.
  6. Remove the existing world or change level-name to a new world name.
  7. Start the server.
The selected seed will be used when Minecraft creates the new world. Important: The seed only affects world generation. Changing level-seed while an existing world is still being used will not regenerate that world.
