Upgrade Neos
It is strongly recommended to create a backup before starting the update process. If you have important data, create and restore a backup to ensure that everything works properly.
You can upgrade the application only without modifying any other stack components using the steps below.
-
Browse to the Neos website.
-
Browse to the “Installation via Composer” section.
-
Install Composer:
$ curl -s https://getcomposer.org/installer | php

Navigate to the Neos installation directory. Depending on your installation type, execute the following command:
-
Approach A (Bitnami installations using system packages):
$ cd /opt/bitnami/neos
-
Approach B (Self-contained Bitnami installations):
$ cd /opt/bitnami/apps/neos
-
-
Install the Neos base distribution with all dependencies:
