TCP to SSL Converstion

It's also worth pointing out that TCP and SSL work at separate layers of the OSI and are more or less independent of one another. In other words, you can't replace TCP with SSL. TCP is a transport protocol and can only really be replaced by UDP. SSL sits between TCP/UDP (layer 4) and any application protocol (layer 7), so in many cases it's just a matter of adding SSL (or not adding it). So as tatmotiv stated, assuming the same application layer protocol on either end, it'll likely be as simple as adding an SSL profile to the virtual server.
