To upgrade SonarQube through a zip file, follow these steps:

1. Download the latest version of SonarQube from the official website: https://www.sonarqube.org/downloads/
2. Backup your existing SonarQube database, logs, and configuration files.
3. Stop the SonarQube server by running the command: ./sonar.sh stop (Linux) or ./sonar.bat stop (Windows) in the SonarQube installation directory.
4. Extract the downloaded zip file to a new directory.
5. Copy the contents of the conf and data directories from your existing SonarQube installation directory to the new directory.
6. Update any custom configurations or settings in the new conf directory if necessary.
7. Start the SonarQube server by running the command: ./sonar.sh start (Linux) or ./sonar.bat start (Windows) in the new SonarQube installation directory.
8. Verify that the SonarQube server is running and accessible by accessing the SonarQube web interface in your browser.
