Hi. I have a vSZ-H 3.2.0.0.790, I need to register some "old" APs (7762, 7363) on this controller. As I know I can do that if I create a new Zone and set an older firmware version. That's right? If yes, how can I upload an older firmware version? (but I don't want to remove the las version, because I need to to define another Zone.
