Changing the version of your Minecraft Server

  1. Stop your server and take a backup
  2. Navigate to “Advanced” tab, and change the Version field to the version you wish to use
  3. In the “Settings” tab, press “Reinstall” to start the update process
  4. Start the server and run /version command to check if the version has been changed
Downgrading server versions is far more difficult as you cannot port whole worlds back versions without a backup. It requires you to manually move builds with schematics, and proper checking for new blocks.
