How to Update a Modpack on Your Minecraft Server
Learn how to safely update an installed modpack to a new version without losing your world.
Updating a modpack requires replacing the server mod files while keeping your world data intact.
Updating a Modpack
Create a backup
Access the XGamingServer panel, go to Backups, and create a full backup.
⚠️ Warning: Always backup before updating. Modpack updates can occasionally break worlds or remove items from removed mods.
Download the new server files
Download the updated modpack server files from the modpack's official page (CurseForge, FTB, etc.).
Delete old mod and config files
Go to Files and delete:
/mods/folder/config/folder/scripts/folder (if it exists)
Do NOT delete: world/ folder, server.properties, eula.txt, or any other settings you've customized.
Upload new files
Upload the new modpack server files. This typically includes new /mods/, /config/, and /scripts/ folders.
Start your server
Start the server and check Console for errors.
Verify the update
Connect and verify everything works. Check for missing blocks/items from removed mods.
💡 Tip: Read the modpack's changelog before updating. Breaking changes will be listed — they may require a world reset.
📝 Note: Tell players to update their client-side modpack to the same version before connecting, or they'll get a Mismatched Mod Channel error.
