How do I change my Minecraft server's version or software (Paper, Forge, Fabric, etc.)?

Changing your Minecraft server's software or version is a one-click job thanks to the Versions tab. It's the canonical way to switch between Vanilla, Paper, Forge, Fabric, and many more — no manual jar uploads required.

The Versions tab

The Versions tab is a built-in, one-click installer. Instead of hunting down jar files, you pick your software and version from a catalog and the panel handles the rest.

Step-by-step

1. Open your Minecraft server and go to the Versions tab.
2. Pick your software — Vanilla, Paper, Spigot, Purpur, Fabric, Forge, NeoForge, Quilt, Folia, Pufferfish, Sponge, BungeeCord, Waterfall, Velocity, and more.
3. Choose the Minecraft version and a build, then install.

Warning: Switching software can change how worlds and plugins load — back up your world first by downloading it from the Files manager.

Frequently asked questions

Do I need to upload a jar manually? No — the Versions tab handles it for you. Manual jars are only for rare edge cases, done via the Files and Startup tabs.

Will switching software break my plugins or mods? It can, because plugins and mods depend on the software family (for example Paper vs Forge). Back up first, and check that your add-ons match the new software before relying on them.
