Switching to experimental version your Satisfactory server
Firstly we’ll need to delete the server files for new ones to be created for the experimental version.
This will delete all of your sessions. Make a backup first if you want to keep them.
1. Open the Fragnet dashboard, go to My servers and select your server. Stop the server with Shut down at the top of the page (see Power controls).
2. If you want to keep your sessions, make a backup on the Backups tab first (see Backups). You can also download only the save folder: on the Files tab, open .config/Epic/FactoryGame/Saved/SaveGames, use Compress in the ⋯ menu of the server folder and Download the archive (see File and folder actions).
3. On the Files tab, go to .config → Epic → FactoryGame → Saved → SaveGames → server and delete the contents of the server folder. To delete everything at once, tick the box in the header of the file list and select Delete.
4. Select the Configuration tab, then General in the list on the left. In the Startup group, find Branch Name, the setting that chooses between the public and experimental branches of Satisfactory, and set it to experimental. Select Save. See Startup.
5. Start your server. It updates to the experimental version when it starts, which can take a few minutes.
6. Done! Your server is now running on experimental mode.
Your game must run the same branch as the server. In Steam or the Epic Games Launcher, switch your game to the experimental version too. To go back, set Branch Name to public and start the server again. Saves made on the experimental version may not load on the public version.
