Upgrade Pimcore

To upgrade Pimcore, follow the steps below:

• First, enable the debug mode by following 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:

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

  Edit the memory_limit value. It is recommended that you restore the default value after you upgrade Pimcore.

    memory_limit = 2048M
  

• Navigate to the /opt/bitnami/pimcore Pimcore installation directory.

• Execute composer update:

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

• Once the upgrade has completed, revert the change to the memory_limit variable in your /opt/bitnami/php/etc/php.ini file to the previous value, and disable the debug mode.
