Terraria World Version Compatibility

Servers cannot load worlds that were created on a later version of Terraria. Update your server or try restoring a backup to keep playing. This guide will show you how to do that in a few simple steps.

World version compatibility prompt

When loading a world that was created or last played on a later version of Terraria, you may see a prompt like this in the server console:

Terraria Server v1.4.5.0

1             (LaterVersion) world1
n             New World
d <number>    Delete World

Choose World:

To keep playing, you can either update your server or try restoring a world backup that was created with an earlier version of Terraria.

Automatic world backups

Terraria servers automatically create backups of your world file each time the game is stopped. The two most recent backups are stored next to your main world file:

gameserver
└── Worlds
    ├── world1.wld
    ├── world1.wld.bak
    └── world1.wld.bak2

If any of these backups was created with an earlier version of Terraria, you can try restoring it to keep playing.

Restoring a backup

1. Start your server
2. Pause your server
3. Open the Config screen
4. Open the Worlds folder under gameserver/Worlds
5. Optional: Download all your world files as a backup
6. Rename world1.wld to world1.wld.old
7. Rename world1.wld.bak to world1.wld
8. Unpause your server
