At a glance Use the server package, match Forge or Fabric and check version and file compatibility.
1. Check the version and requirements
Save the Minecraft version, loader (most often Forge or Fabric) and memory requirements. Check the instructions of the modpack creators. Examples of popular packages include Better MC, Pixelmon, All The Mods, RLCraft and Prominence — each may require its own version, loader and settings. Do not assume that two packages with a similar name use the same files.
2. Download Server Pack
If the author shares the server version, download it. The client package may not contain startup files, libraries or configurations required on the server.
3. Make a backup and stop the server
Stop the service and download the backup of the world and the current files. Do not overwrite the existing world until you check if it is compatible with the new version of the package.
4. Upload Files and Set Loader
Unpack Server Pack and move compatible folders, including mods and config, to the server directory. In the panel, select the right loader and game version. When installing VPS manually, it also requires a compatible version of Java.
5. Run the test and check the console
The first start can take longer. If the server stops, read the earliest error in the log: it often indicates missing mod, incompatible loader or Java. Each player should install exactly the same modpack version.
Back up first. Change one thing at a time.
Back up your working files, make a change and check the logs. Changing one thing at a time makes it easier to find the cause of a problem and restore your previous settings.
