How to Convert Minecraft Bukkit World to Vanilla

Converting Bukkit Worlds to Vanilla

If you upload or generate a world on a Bukkit/Spigot/Paper server, you will notice that when the server loads it splits the world into three folders: world, world_nether and world_the_end, or one for each dimension.

This is fine until you want to download the world and run it in singleplayer or switch to a vanilla/Fabric/Forge server. This guide shows you how to convert Bukkit/Spigot/Paper worlds back to ones that can be used on vanilla or other server types.

Part 1: Download the World

Note: This is not strictly necessary — you CAN use SFTP or the file manager if you want, but downloading the files makes them much easier to work with.

This is most easily done by archiving the files using the Pterodactyl file manager and downloading them using SFTP.

Part 2: Converting the World

Once you have downloaded and extracted your archive from the server, you should have three folders:

• world
• world_nether
• world_the_end

We will refer to the folder where these folders are located as the "root" folder.

Step 1 — Copy the Nether

1. 1Go into world_nether and copy the DIM-1 folder (ignore everything else)
2. 2Return to the root folder
3. 3Open the world folder and paste the DIM-1 folder there

Step 2 — Copy the End

1. 1Return to the root folder and go into world_the_end
2. 2Copy the DIM1 folder
3. 3Paste it in the world folder, just like the DIM-1 folder

Result

By copying the DIM-1 and DIM1 folders into world, you have made a copy of all the data of the Nether and End dimensions available in the world folder.

The world folder now contains all the required data to run all three dimensions successfully and can be run without issue on vanilla, Fabric, Forge and other servers.

Congratulations, you did it!
