I ran a small self-hosted Bukkit server for Minecraft version 1.5.2 and later 1.16

I only used a few plugins, e.g. a AutoBackup, nothing game-changing.

Now, for different reasons, I wanted to switch back to Vanilla starting from version 1.16.1. But the Bukkit server stored the world in three separate folders:

  • WORLDNAME_nether
  • WORLDNAME_the_end

How can I combine those folders to make the server compatible with a Vanilla server again?
