I'm following the official guide to upgrade angular app to version 10 , currently while try to upgrade to CLI version 6 as per the update.angular.io
Make sure you are using Node 8 or later Update your Angular CLI locally, and migrate the configuration to the new angular.json format by running the following:
npm install @angular/cli@6
ng update @angular/cli@6
I've run the following code but still i could see .angular-cli.json file instead of angular.json file.
Below is current cli version updated to version 6 except for couple of warning related to peer dependency didnt get any error while updating CLI.
