he task After the Dynamics NAV 2018 CU2 release, I found it safe to upgrade my own Dynamics NAV 2016 solution up to Dynamics NAV 2018. But not only that, ALL changed objects should be transferred to extensions. My system is a small solution and it started in NAV 4.0. On every upgrade process, I have tried to kill all the changes in the system and to start all over, in order to utilize as much of the new standard functionality as possible.
