🔄How to Change Your Server Version

Introduction

You can swap Minecraft versions any time, go from 1.20.1 to 1.21, switch Paper to Purpur, or roll back if an update breaks your mods.

Before You Change Anything

1. 1Stop the server from the Console tab
2. 2Open Backups → Create Backup and wait for it to finish
3. 3Copy your backup name somewhere safe

This single backup will save you if anything goes wrong.

Switch Versions

1. 1Open Settings → Server Type & Version
2. 2Pick the new server software (Vanilla / Paper / Purpur / Forge / Fabric)
3. 3Pick the version number from the dropdown
4. 4Click Save & Reinstall
5. 5The panel downloads the new JAR, wait until it says Ready
6. 6Click Start on the Console tab

Things That Might Break

• Plugins, built for old versions may not load. Re-download for the new version
• Worlds, usually upgrade fine forward, but downgrades can corrupt chunks
• Datapacks, version-specific, check compatibility
• Resource packs, pack format changes between major versions

Tip: For modded servers, never downgrade Forge/Fabric with the same world. Always test on a fresh copy first.

Rolling Back

1. 1Settings → Backups
2. 2Find the backup you made earlier
3. 3Click Restore
4. 4Confirm, the panel reverts everything
