Upgrading EMS to 7.4.6 and SSL VPN hidden by default

Hello,

Planning to upgrade our EMS instance to 7.4.7 (currently on 7.4.5) and one of the ‘new features’ listed for 7.4.6 is hiding the SSLVPN feature by default (https://docs.fortinet.com/document/forticlient/7.4.0/new-features/483736/ssl-vpn-feature-select-option-is-hidden-by-default-7-4-6). With one of our Remote Access profiles including an SSLVPN profile, does anyone know the expected behavior or impact this may have?

IE, once the upgrade is completed, will re-connected endpoints lose their SSLVPN configuration from the remote access profile? We are planning to re-enable the SSLVPN feature post upgrade via the cli commands provided but want to plan accordingly if the upgrade may wipe out the configuration until the feature is re-enabled. 

I would anticipate we will have some sslvpn connections active during the upgrade and don't want active users to get booted unintentionally. 

Thanks!
