If you have already started in a local world, or want to e.g. choose custom seed, then it is useful to be able to upload a local world to Valhost. This is how you do it.
1. Find the world locally
All world files are stored in the following folder:
C:\Users\%username%\AppData\LocalLow\IronGate\Valheim\worlds
Glue into e.g. Run-wind to easily open the folder. (WIN + R)
2. Upload to Valhost
Log in to the control panel, https://panel.valhost.no
Find the server you want to upload to.
Stop the server first.
Go to «File manager».
Navigate to the folder:
.config/unity3d/IronGate/Valheim/worlds
Upload the files from your local folder that have the same name as the world you want to move. For example:
MyWorld.fwl
MyWorld.db
Change the startup world
In the control panel, find the «Startup» tab. Change the value under «World Name» to (exactly) the name of the world you uploaded. Restart the server.
