Bringing your existing builds and progress to Fern is a great way to keep your hard work while moving to a better host. Whether you're moving from a local PC or another provider, here's how to do it safely.

1. Prepping Your World

Before you start the upload, make sure your world folder is "clean." You only need the essentials:

level.dat
region/ folder
data/ and poi/ folders

The Secret to a Fast Upload: Don't upload the folder directly. Compress it into a .zip file first. It's much faster and prevents files from getting corrupted during the transfer. Moving from another host? See our Transfer Guide for some extra tips.

2. Open the File Manager

In Mission Control, click on your server.
Hit the File Manager tab in the sidebar. This is where all your server's "guts" live.

3. Upload and Extract

Drag and drop your .zip file into the window.
Once the bar hits 100%, right-click the file and select Extract.
Take note of the folder name that appears (like MyWorld).

4. Switch the Active World

The server doesn't know you uploaded a new world yet. You have to tell it which folder to use.

Go to your server Settings.
Find the World Name (or level-name) field.
Type in the exact name of the folder you just extracted.
Restart the server to load it up.

[!TIP] Just in case anything goes wrong, take a Backup Snapshot of your existing files before you overwrite them with the new world.
