How to Downgrade/Change Minecraft Version for a Server
Many servers run a specific version — sometimes older than your current one. You can switch (or downgrade) your Minecraft version safely using the official launcher. Here's the exact process.

Versions & PlatformsYou don't need to reinstall
The official Minecraft launcher keeps every version you've played as a separate “installation.” Switching is just picking a different profile — your worlds and saves stay put (though older versions may not open newer worlds). Check the server's required version on its detail page first.
Steps in the Java launcher
- Open the Minecraft launcher and go to the Installations tab.
- Click New Installation.
- Under “Version,” open the dropdown and pick the exact release the server wants (e.g.
1.21.4or1.8.9). - Name it, save, and select it from the play dropdown before hitting Play.
A note on modded servers
If the server uses Forge or Fabric mods, you'll need that mod loader installed in the profile too — the server usually links the exact loader version. For vanilla servers, the base game version is enough.
Find servers by version
Our server list has a version filter so you can pick a community that matches whatever client you're on — whether that's the latest or a classic like 1.12.
