Drupal: Core update - simple guide

Drupal is a popular content management system whose core you should update regularly so that everything works exactly as it should. To make sure you don't lose any important website data, it is recommended to make a backup beforehand.

Preparing for updating Drupal Core

The CMS Drupal consists of a core, in German "Kern", and various add-on modules that supplement the application with the functions you need. However, since the core of Drupal provides the basic framework, you need to update it regularly. To create a backup beforehand, so you don't lose any data, use an add-on module:

1. Install "Backup and Migrate" for Drupal.
2. Follow the module's instructions to back up your website.

Perform Update

1. Place your website in maintenance mode via "Configuration > Maintenance Mode".
2. Download the latest version with which you update the Drupal core and unzip the file on your computer.
3. Log into the server via FTP.
4. Now remove all data in the root directory except ".htaccess", "robots.txt" and "sites". These three folders must absolutely remain.
5. Now copy or move all the files of the downloaded and unzipped Drupal core version to the root directory. Nur die drei bestehenden Ordner dürfen Sie nicht überschreiben oder ersetzen.
6. Rufen Sie nun den Browser auf. Geben Sie die URL Ihrer Website ein, schreiben Sie „/update“ dahinter und folgen Sie den Anweisungen, um das Updaten des Drupal Core fertig zu stellen.
