Minecraft is a game defined by its eras. From the classic 1.8.8 PvP builds to the latest 1.21+ updates, managing your server version is a core part of being a server owner.

Technical Requirements

Unlike standard Steam games that auto-update, Minecraft requires a specific Java runtime to match the game version. Using the wrong Java version will prevent your server from starting.
MC VersionRecommended Java
1.18 - 1.21+Java 17 or Java 21
1.17.xJava 16
1.8 - 1.16.5Java 8 or Java 11

Step-by-Step Installation

1. Preparation & Backups

Switching versions—especially downgrading—can permanently corrupt your world files.
  • Always create a Backup of your /world/ directory before proceeding.
  • If performing a “Clean Install,” use the Reinstall button in the Settings tab.

2. Changing the Java Environment

  1. Navigate to the Startup tab in your control panel.
  2. Locate the Docker Image dropdown.
  3. Select the Java version that matches your intended Minecraft version.

3. Updating the Server Software

You can update your server using the built-in version manager:
  1. In the Startup tab, locate the Server Version (or VERSION) variable.
  2. Type your desired version (e.g., 1.20.4, latest, or snapshot).
  3. Click Settings -> Reinstall. The panel will automatically fetch the correct JAR for you.
