Step-by-step guide

1

Open the local save folder

In Palworld, select your save.

Click the folder icon at the bottom left.

The save folder opens.

2

Upload the save to the server (map + world)

In the FTP, go to:

Pal/Saved/SaveGames/0/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/

This is a folder with 32 characters (random).

Copy your local save files into it.

Do not copy WorldOption.sav.

Otherwise your server settings may be ignored.

Do not copy the backupsfolder. It is useless here.

3

Start the server and create a “new” character

Start the server.

Connect in-game and create a new character (temporary).

circle-check

At this point, the map should be correct.

We will now migrate the players.

4

Download the updated server files

Turn off the server.

In the FTP, go back to:

Pal/Saved/SaveGames/0/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/

Download this folder to your PC.

Put it in a new folder (to avoid mixing).

circle-check

In players, you will see a new file .sav.

This is the “temporary” character created on the server.

5

Convert / migrate the player's data

Download the tool palworld-host-save-fix :

Windows Defender / an antivirus may block it.

Verify the source and decide according to your security policy.

Open the application.

Click Browse.

Select the file Level.sav from the folder downloaded in the previous step.

On the next screen:

  • List 1: select the old character (local).

  • List 2: select the “temporary” character (server, level 0).

Click Migrate.

Confirm the confirmation.

6

Re-upload the converted files to the server

In the FTP, send the modified files back to:

Pal/Saved/SaveGames/0/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/

Restart the server.

Reconnect. You should find your progression.
