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 Software page. It's the canonical way to switch between Vanilla, Paper, Forge, Fabric, and many more — no manual jar uploads required.

The Software page

The Software page is a built-in, one-click installer. Instead of hunting down jar files, you pick your software and version from a catalog and it handles the rest. Your world is kept: any files it replaces are moved to a _previous folder.

Step-by-step

1. Open your Minecraft server and go to the Software page (or click the Version chip at the top of the console).
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, for example with Back up now on the Backups page or by downloading it from the Files manager.

Frequently asked questions

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

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.
