Server switching

I have the need to quickly and seamlessly switch a Fire TV Stick client between two or more servers. This is not quite like the scenarios previously discussed. The two servers are in separate networks and different time zones. It works fine to go to the settings and type in (or select) the desired IP address, albeit somewhat clumsy and geeky. However, the client seems to be keeping some data cached. For example, it still shows the guide from the previous connection. Forcing the client to restart clears it, but that's less than ideal.
