Login to your panel at https://game.polisystems.ch or via your client area (if you didn't setup your account yet watch your mails)
Once there click on manage.
Here you will have a full view of your Factorio server.
Once you are there go to Configuration > Startup Parameters
Change your version in Factorio version and remember to click on Update Startup Parameters you can choose between multiple versions (experimental, latest, or custom a list of version can be found here https://updater.factorio.com/get-available-versions)
Now move to the advanced tab, simply 2 buttons left of the Startup Parameters.
Here press on the reinstall button (yes the red one) and press OK. We recommend you to download your saves before, however, we never have lost any saves during the process. It's written, All data will be lost, but only factorio binaries will be touched.
Once you have pressed wait a few seconds (10-30) usually. And you will be redirected again to the page. Go in System > Console and start your factorio server again. You will see once you have understood it's truly 2 clicks. If there are a new update and you are set on experimental (and there is one new experimental update out) press on reinstall the server. Have fun!
