Manually Upgrading the owncloud Instance on Your Linux Server

As I have to do it every now and then, here are the important steps of the upgrade workflow:

• Backup the whole folder (/var/www/owncloud) using, e.g.

  cp -a owncloud backup_folder

• Activate the maintenance mode (in owncloud folder):

  sudo -u www-data php occ maintenance:mode --on

• Download the new owncloud archive and “replace” the existing folder (including .htaccess file)
• Replace back the config/config.php file from the backup_folder and the data folder
• Run the upgrade:

  sudo -u www-data php occ upgrade

• Switch back to normal mode:

  sudo -u www-data php occ maintenance:mode --off
