HI Tushar, 
 Which SDK are you using? After looking at some of your former threads, I will assume you use the nRF Connect SDK for now. 
 the DFU process will start and complete but thread will be running simultaneously how can i stop my current application 
 
 This is normal. MCUboot, which is the bootloader used in the nRF Connect SDK, does not have BLE transport, so the transport happens in the application, which then includes the management subsystem. So your application will run during the DFU process, up to the point of activation, where a reset happens. 
 If you want to do something in your application (like stop doing what it does, cleanup or something else), you can register relevant callbacks with img_mgmt_register_callbacks() or img_mgmt_set_upload_cb().
