How to Change Your Minecraft Server Version

Change your server version to access new features or maintain compatibility with players.

​
Changing the Version

  1. Stop your server and create a backup
  2. Go to the Startup tab and change the Version field
  3. Go to the Settings tab and click Reinstall
  4. Start your server and run /version to verify
Downgrading is difficult and can corrupt worlds. Always backup first and check for incompatible blocks.

​
Java Version Requirements

If you get a Java error, change the Java Version in the Settings tab:
  • Java 8: Minecraft 1.14 - 1.16.5
  • Java 16: Minecraft 1.17 - 1.17.1
  • Java 17: Minecraft 1.18+ (Recommended)
  • Java 18-21: Latest versions
