Issue
After migrating application from angular 5 to 6, on running ng serve the following errors pop up.
Schema validation failed with the following errors:
Data path “” should NOT have additional properties(project).

I assume that the error is with .angular.json file which I re-named from .angular-cli.json .
My .angular.json file is as follows :
{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",

"name": "mediaweb"

Should I re-structure the json file, if so how?.
Any help would be great.
Solution
Since I fixed the issue I thought it would be nice to post it here.
I changed my file name .angular.json to angular.json and replaced some properties from the question in it.

I changed the file by replacing the angular.json file with properties in the angular official docs.
The official Angular Update Guide provides a step by step guide on how to update versions.
