SSL & http

I have a web licensing server application (Xojo Web app) on my Xojo Cloud. My desktop application communicates with the web application to handle authenticating its license. The web application handles these requests through the HandleSpecialURL event. I want to move to SSL for future versions of the desktop application. If I enable SSL on my Xojo server, will existing users desktop applications no longer be able to access the web application without an SSL connection ? The current desktop application uses the HTTPSocket (Xojo 2016 r1.1). I know that I will need to use HTTPSecureSocket when I want an SSL connection in future desktop application version. Any thoughts or help much appreciated.

Existing apps would not be rejected so what you describe will work just fine. You would have to actively reject them.
