DFU from SDK16.0 to SDK17.2

DFU from SDK16.0 to SDK17.2https://devzone.nordicsemi.com/f/nordic-q-a/70690/dfu-from-sdk16-0-to-sdk17-2Hi, I am trying to test the eligibility of updating my project from SDK 16.0 to 17.2 using DFU. I programmed just softdevice and bootloader of SDK 16.0 and made a package containing bootloader, softdevice and application of version 17.2.
