# How to Change Your Terraria Server World Name (/docs/terraria/rename-server)



import { Tab, Tabs } from 'fumadocs-ui/components/tabs';
import { Step, Steps } from 'fumadocs-ui/components/steps';

Terraria doesn't have a separate "server name" or "hostname" like most multiplayer games. Instead, the **world name** doubles as the server identifier — it's what players see when they connect and what's used as the save file name.

| -------------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| **Case-sensitive on Linux**      | `MyWorld` and `myworld` are different worlds                                                                          |
| **No spaces in some setups**     | Underscores or CamelCase are safer than spaces                                                                        |
| **Renaming creates a new world** | If you change the world name and the new name doesn't match an existing `.wld` file, Terraria generates a fresh world |
| **Existing worlds preserved**    | Your old world stays on disk — switch back by restoring the original name                                             |

Switching Between Worlds [#switching-between-worlds]

Because the world name determines which save loads, you can host multiple worlds and swap between them by changing this setting:

1. Stop the server
2. Change `worldname` to a different value (e.g., `Hardcore` instead of `Casual`)
3. Start the server — Terraria loads (or generates) the world with that name
4. Switch back later by changing the name again
