Upgrade Ortro

Upgrading from version x to version y is simple as overwriting the old Ortro installation directory with the new one.
Just remember to check ownership and permission especially for the configuration directory (i.e. conf).

# chmod 700 $ORTRO_HOME/conf

When the upgrade require to alter the database structure, you will find a folder with the relative scripts, enter in the folder and exec the upgrade.php script:

# cd $ORTRO_HOME/upgrade
# php upgrade.php
