configuration of multishop prestashop 1.7

[gabbodrummer]

i have to migrate from prestashop 1.6 to prestashop 1.7, in the new version i have made a multishop site. 
how should I set the httpd.conf and the conf file of the related site for it to work?
now my conf site file is:

        

<VirtualHost *:80>
            ServerAdmin [email protected]
            ServerName www.example.it
        ServerAlias example.it

            <Directory />
                    Options FollowSymLinks
                    AllowOverride None
            </Directory>
            <Directory /home/sites/www.example.it/web/>
                    Options Indexes FollowSymLinks MultiViews
                    AllowOverride None
                    Order allow,deny
                    allow from all
                    Require all granted
            </Directory>
            AddType application/x-httpd-php .php5
            AddType application/x-httpd-php .php4

            RewriteEngine on

            Header always set Strict-Transport-Security "max-age=63072000; includeSubdomains;"
    php_admin_value open_basedir "/home/sites/www.example.it:/home/sites/www.example.it/private:/home/sites/www.example.it/tmp:/tmp"
    php_admin_value session.save_path "/home/sites/www.example.it/tmp"

        </Directory>
    </VirtualHost>

What should I add or change in this file?
is there any other file I need to change?

It shouldn't really be necessary, you can just set the other domain in cpanel/plesk to point to the main prestashop directory, then create the url for the multishop context
