*** It is strongly encouraged to create a backup of both, your web data and your database!***
Start by downloading the new version from Sourceforge. The latest version is always available at https://sourceforge.net/projects/commsy/files/latest/download. Extract the archive and upload it to your LAMP environment near to the current CommSy version.
Notice: Do not overwrite your current installation of CommSy.
It is always a good idea to use symlinks pointing to the current commsy version like this:
:::
.
..
commsy_8.x.y
commsy_8.x.z
current -> commsy_8.x.y
Copy the configuration files from the old version to the new version. This includes:
- etc/cs_config.php
- any files under etc/commsy/ ending with .php (not .php-dist)
Copy all directories under var/ from the old version to the new version.
Go to the CommSy Server page (the page listing all available portals) and follow the server configuration link. You can execute all available database update scripts under "Update".
