Upgrade Pimcore

First, it is necessary to enable debug mode by editing /opt/bitnami/apps/pimcore/htdocs//var/config/debug-mode.php file as below:

  "active" => TRUE,

Access the administration panel, click on “Tools -> Update” menu and select a version as it is shown in the image below:

You will be prompted to run composer update. Follow these steps:

• Set the memory_limit variable in your /opt/bitnami/php/etc/php.ini file to 2048M. To know the total memory available, execute the command free -h. Modify the memory_limit value using the terminal:

    $ sudo nano /opt/bitnami/php/etc/php.ini
  

• Edit the memory_limit value. It’s recommended that you restore the default value after you upgrade Pimcore.

    memory_limit = 2048M
  

• Execute composer update:

    $ sudo su daemon -s /bin/bash -- /opt/bitnami/php/bin/composer update
