[quote user=""]I think this result will happen too when doing DFU, because DFU is only re-program the application flash area, not erase nwk/opt/access/device-manage flash area.[/quote]

Why do you believe that the DFU only updates the application area & not the network/opt/access/device-manager flash area?

The way I understand it, when you do a DFU, you update the whole application. That means that the mesh stack, as well as your application will be updated. This is because the mesh stack is a part of the application build hex file.

[quote user=""]So, is it possible that upgrade a device(already provsioned and configured) from sdk2.2 to sdk3 and boot up successfully?[/quote]

Yes, this is possible. Have you tried doing a DFU using our example? This documentation could also be helpful.
