1. Backup First!
Always create a backup before updating:
- Go to the Backups tab.
- Click Create Backup.
- Wait for the ZIP file confirmation.
2. Switching Versions
- Go to Settings > Server Version.
- Select the new version (e.g., 1.20.1 to 1.20.4).
- Click Install/Update.
Your world and configs usually remain, but some plugins/mods may break if they don't support the new version.
3. Automatic Migration
The app handles migration to the new Java system automatically:
- Verifies the current server version.
- Checks for the appropriate Java runtime.
- Downloads and links the correct version if missing.
4. Mods & Plugins
You'll likely need to update mods manually. Use the Search & Install feature (v2.0.0+) to find matching versions quickly.
