Moving Your World to Fern

Moving your world to Fern is like moving into a new house; we've made the "heavy lifting" as easy as possible. Whether you're coming from another hosting provider or just moving a single-player save you've been working on for years, it only takes a few minutes to get everything set up.

The Migration Guide

The Zip: On your old server (or your computer), zip up your world folder. Make sure the level.dat file is inside the main zip folder, not buried deep in sub-folders.
The Upload: Open Mission Control > Files. Simply drag and drop your .zip file into the main area.
The Extraction: Right-click the uploaded zip and hit Extract. [image - Mission Control > Files | File Actions | Showing a .zip file selected with the 'Extract' option visible in the context menu]
The Handover: Now you need to tell the server to load that specific folder:
- Go to Settings > World.
- Change the Level Name to match your folder name exactly (e.g., SurvivalWorld).
- Hit Save. [image - Mission Control > Settings | Game Properties | Highlighting the 'Level Name' field to match the uploaded folder name]
The Launch: Start your server!

Moving Between Fern Servers

If you have multiple servers with us and want to move a map from one to the other:

Create a Snapshot on the first server and download it to your computer.
Follow the steps above to upload it to your second server.

[!IMPORTANT] Check Your Version: You can always move an "old" world to a newer version of Minecraft, but you cannot go backward (like moving a 1.21 world to 1.20). Doing so will likely corrupt your beautiful chunk generation and delete your items.

Troubleshooting

"Why is my world fresh?": If you join and it’s a brand new world, the Level Name in your settings didn't match the folder name exactly. Double-check the spelling (it’s case-sensitive!).
"Where are my modded items?": If your world used mods on your old host, you must install those same mods on Fern before you join, or all your modded blocks will vanish.
