Can COA be used to change SSID of a device. I am trying to set up packet fence as captive portal solution. Here is what I found in documentation

On wireless networks, the usual PacketFence setup dictate that you configure two SSIDs: an open one and a secure one. The open one is used to help users configure the secure one properly and requires authentication over the captive portal.

I am trying to understand how COA can change SSID on the device

No, it can't.

CoA can change attributes of an existing connection (disconnect a user, apply different policy etc.), but SSID selection is a function of the wireless client (think Layer 1), not the authentication process (Layer 2).

If you think about it from a Wired network perspective, that would be like trying to use CoA to patch a user into another port.
