Linking your Kasa Cameras to the Tapo App does not stop the KasaCare service, as those cameras can still be managed in the Kasa App.  However, if you are subscribing to TapoCare for the other two cameras it would be cheaper to subscribe to a TapoCare account plan which will allow you to have cloud storage for up to 10 cameras.  However, if you want the Kasa Cameras to be part of the TapoCare plan you would have to cancel the KasaCare coverage first.  There is no way to transfer a KasaCare subscription to TapoCare.
