I am upgrading the angular version from 2 to 6 by following the Angular Update Guide, but after migrating Angular CLI globally and locally, it could not generate the angular.json file. The project includes systemjs.config.js, it did not have angular-cli.json file, nor @angular/cli dependencies in package json. What can be done to solve this?
