How to change the Paper or Purpur version

Use this guide if your server runs the Paper or Purpur egg and you want to change the Minecraft server version.

Before you start

Back up the server first. Changing versions can affect world, plugin, and config compatibility.

1. Download the official build

Make sure you grab the .jar file that matches the Minecraft version you want to use.

2. Upload the file to the panel

  1. Open https://panel.nexuscloud.id/.
  2. Select your server.
  3. Go to Files.
  4. Upload the .jar file you downloaded.

3. Adjust startup

  1. Go to Startup.
  2. Change the Minecraft Version variable if your egg provides one.
  3. If the startup expects a specific file name, rename the .jar to match what the egg requires, for example server.jar if that's what the server startup calls for.

4. Restart the server

  1. Go back to Console.
  2. Restart the server.
  3. Wait for the boot to finish.
  4. Run the version command in the console to confirm the active build is correct.

Important notes

  • Don't delete the old world or configs unless you have a clear compatibility error.
  • A major Minecraft version bump can break compatibility with some older plugins or datapacks.
  • For modern Paper or Purpur servers, also check the Java version required by the build you use.

If errors appear after the update

  • Check for incompatible plugins.
  • Restore a backup if needed.
  • Make sure the startup file points to the right .jar.
