"DeviceModeInd" MAC command response from network server

My end device is LoraWAN 1.1.0 compliant, so it sends the mac command “DeviceModeInd” uplink to the server to indicate that it wants to operate as a class C device. If this device is assigned with a device profile that is configured with LoraWAN MAC version 1.0.3 in the server, Since this MAC command “DeviceModeInd” is supported only in MAC version 1.1.0, should the server respond to “DeviceModeInd” with a downlink ? or It should not respond for this ?
