Updating your Valheim server to 1.0 ensures that your dedicated server and everyone connecting to it are running compatible versions of the game. If players update their game while the server remains on an older build, they may be unable to connect or receive an incompatible version error.

How you update depends on where your server is running. A self-hosted Valheim server requires you to manage the installation, files, backups, and update process yourself. With dedicated Valheim hosting, the hosting environment can handle most of that work automatically.

This guide covers both methods, including how to update Valheim 1.0 with SteamCMD and how existing or new Pine Hosting servers handle the update.

What To Do Before Updating Your Valheim Server To 1.0

Before updating, create a backup of your Valheim world.

Server updates normally replace game files rather than intentionally removing world data, but a recent backup protects the progress stored on your server if something goes wrong or you need to restore your previous setup.

For a standard self-hosted installation, Valheim data is normally stored at %USERPROFILE%\AppData\LocalLow\IronGate\Valheim on Windows.

If you use the -savedir startup argument, your world may be stored somewhere else.

You should also protect your startup configuration. Valheim provides start_headless_server.bat on Windows. If you have customized these files with your world name, password, ports, or other parameters, use your own copy because the original startup file can be replaced when the dedicated server is updated.

If you are also unsure whether you want to keep your existing Valheim world or start fresh for 1.0, it is worth making that decision before changing your server setup.

How To Update A Self-Hosted Valheim Server To 1.0

Running Valheim servers from your own PC gives you direct control over the installation, but it also means you are responsible for keeping the dedicated server software updated.

First, stop the server completely. If Valheim is running through a command window, use CTRL+C to shut it down properly before changing any files.

Once the server has stopped and your world is backed up, update the Valheim Dedicated Server installation. If you installed the dedicated server through Steam, make sure the Valheim Dedicated Server tool in your Steam library has downloaded its latest update.

For servers managed through SteamCMD, you need to manually update the server application.

How To Update Valheim 1.0 With SteamCMD

The Valheim Dedicated Server uses Steam App ID 896660.

If SteamCMD is installed at C:\steamcmd and your existing server is located at C:\ValheimServer, you can update it using:

C:\steamcmd\steamcmd.exe +force_install_dir "C:\ValheimServer" +login anonymous +app_update 896660 validate +quit

Replace C:\ValheimServer with the directory containing your actual dedicated server installation.

The command works as follows:

  • +force_install_dir selects the existing server installation you want to update.
  • +login anonymous connects SteamCMD without requiring your personal Steam account.
  • +app_update 896660 downloads the latest Valheim Dedicated Server version.
  • validate checks the installation and replaces missing or incorrect files.
  • +quit closes SteamCMD when the process finishes.

Wait until SteamCMD confirms that the application has been successfully updated before launching the server again.

For Linux, the same process applies with different directory paths. For example, your command could be steamcmd +force_install_dir "/home/steam/valheim-server" +login anonymous +app_update 896660 validate +quit.

After the update completes, launch the server again using your normal start_headless_server.bat.

How To Check Your Valheim Server Is Running 1.0

Once the server starts, watch the console for errors and allow it to finish loading before attempting to connect.

Then connect using an updated Valheim client. If the server starts correctly and updated players can enter the world without a version mismatch, the update has been applied successfully.

This is also a good time to check other parts of your setup. If you use mods, Valheim 1.0 mod compatibility should be checked separately because updating the dedicated server does not automatically update BepInEx or individual mod files.

Once the server itself is working correctly, you can also review your Valheim 1.0 world modifiers and server settings if you want to make gameplay changes for the new version.

Fixing Valheim 1.0 Incompatible Version Errors

An incompatible version error usually means the player and server are not running compatible Valheim builds.

Make sure both the game client and dedicated server have completed their updates. If you used SteamCMD, check that +force_install_dir points to the server installation you actually launch.

This is an easy mistake to make if several Valheim server installations exist on the same machine. SteamCMD may successfully update one folder while your startup script continues launching an older installation elsewhere.

If the server is modded, outdated mods can create additional compatibility problems. If the server is updated correctly but performance becomes the problem instead, larger Valheim servers can also require additional performance optimization as worlds, bases, and player activity grow.

How To Update A Valheim 1.0 Server With Pine Hosting

With Pine Hosting, you do not need to manually download SteamCMD, enter update commands, locate dedicated server directories, or replace files yourself.

Starting A New Valheim Server

If you do not already have a server, purchasing a new Pine Hosting Valheim service automatically deploys the server with the latest available Valheim version installed.

There is no older version that you need to update from and no manual Valheim 1.0 installation required. Once the service is deployed, you can configure your world and other server options through the Pine Hosting game panel.

If you are comparing providers before starting, choosing the best Valheim hosting should also take into account updates, backups, performance, file access, and how easily the server can be managed.

Updating An Existing Pine Hosting Valheim Server

If you already have an active Pine Hosting server, updating it to Valheim 1.0 only requires a few steps:

  1. Stop your Valheim server.
  2. Open the Backups tab and create a fresh backup.
  3. Go to the Start tab.
  4. Make sure Auto Update is enabled.
  5. Restart the server.

When the server starts with Auto Update enabled, Pine Hosting automatically fetches the latest Valheim server files required for the update.

There is no manual SteamCMD process or dedicated server installation required.

Host Your Valheim 1.0 Server With Pine Hosting

Self-hosting gives you control over the entire server environment, but updates also mean managing SteamCMD, directories, startup files, backups, and troubleshooting yourself.

With Pine Hosting Valheim hosting, new servers automatically deploy with the latest version, while existing servers can update by creating a backup, enabling Auto Update, and restarting through the panel.

Whether you are bringing an existing world into Valheim 1.0 or creating a completely new server, Pine Hosting removes the manual server-update process so your group can focus on playing.
