How to Update Your ATM10 Server (2026)

All The Mods 10 receives frequent updates that add content, fix bugs, and update mod versions. Updating your server correctly is critical because a version mismatch between client and server means players cannot connect. Here is how to update safely.

Before you update

1. Back up your world. Copy the entire server folder or use your panel's backup feature. If the update breaks something, you need this backup to roll back.
2. Check the changelog. Read the ATM10 changelog on CurseForge or GitHub to see if any mods were added or removed. Removed mods can delete blocks from your world.
3. Match versions. Your server and all clients must run the exact same ATM10 version. Coordinate with your players before updating.

Step-by-step update process

1. Stop the server completely.
2. Download the new ATM10 server pack from CurseForge or Modrinth.
3. Extract the new server files into a temporary folder.
4. Copy the new mods folder into your server, replacing the old one.
5. Copy any updated config files. Be careful not to overwrite your custom configs (server.properties, whitelist, etc.).
6. Update the NeoForge version if the changelog requires it.
7. Start the server and watch the console for errors.
8. Have one player test the connection before announcing the update.

Common update errors

• Mismatched mod versions: a mod on the server is a different version than on the client. Check the error message for the exact mod name and version.
• Missing mods: a new mod was added in the update but you did not copy it. Recopy the entire mods folder.
• World corruption warning: if a mod was removed that placed blocks in your world, the server may log warnings. These blocks become unknown blocks but usually do not crash the server.
• Java version mismatch: ATM10 requires Java 21. If you updated NeoForge, make sure Java 21 is still the active runtime.

On managed hosting

On a managed host like Space-Node, you can update through the control panel:

1. Stop the server.
2. Use the file manager to upload the new mods folder.
3. Start the server.

Some hosts offer one-click modpack updates. Check if your panel supports reinstalling the server pack while keeping the world folder.

The short answer

Back up first, replace the mods folder with the new version, match NeoForge if needed, and make sure all clients update to the same version. Test with one player before opening to everyone.

Space-Node Minecraft plans support ATM10 with NeoForge and Java 21 pre-configured. See our modpack hosting page or the full Minecraft plans.
