Switch software/JAR (Paper/Purpur/Spigot/Vanilla)
Change your Victus server between Paper, Purpur, Spigot, Vanilla, Fabric, Forge or Velocity — via the Startup variables or an egg change, backing up first.
The server software (the JAR) determines what your server can do: Vanilla is stock Minecraft; Spigot/Paper/Purpur are Bukkit-based and support plugins (Paper and Purpur add big performance gains); Fabric/Forge run mods; Velocity is a proxy that links multiple servers. On Victus the software comes from the server's egg, and some variants can be selected from the Startup tab.
| Software | Plugins | Mods | Best for |
|---|---|---|---|
| Vanilla | No | No | Pure, unmodified Minecraft |
| Spigot | Yes | No | Plugins, basic optimisation |
| Paper | Yes | No | Best all-round: plugins + strong performance |
| Purpur | Yes | No | Paper plus extra tweaks/customisation |
| Fabric | No | Yes | Lightweight mods / modpacks |
| Forge | No | Yes | Large mods / classic modpacks |
| Velocity | Proxy plugins | No | Linking multiple servers behind one address |
Switching between Bukkit-based and modded software, or changing the egg, can require a reinstall that wipes server files. Create a Backup and/or download your world before you start.
Switch it
- Back up (Backups tab) and note your current MC version.
- If your egg exposes a software/type variable, open the Startup tab, set it (e.g. Paper → Purpur, both Bukkit-based so the world stays), save and Restart.
- To move between families (e.g. Vanilla/Paper ↔ Forge/Fabric) you likely need a different egg — do a Reinstall from the Settings tab, or ask support to change the egg on your service.
- After it boots, re-add your plugins (Bukkit types) or mods (Fabric/Forge) as appropriate.
Vanilla, Spigot, Paper and Purpur share a world format, so moving between them normally keeps your world. Moving to/from modded (Forge/Fabric) can change the format and behaviour — test on a copy if the world matters.
