To update Angular CLI to the latest version, which is right now 10 then, you need to update the global packages. If you are starting a brand new angular project, then you need to update comprehensive packages. Still, if you want to upgrade an existing project, then you have to update project-specific packages as well.

You can perform the necessary update to the current stable release of the core framework and CLI by running the ng update @angular/cli @angular/core commands. To upgrade to the next beta or pre-release version, you can use the –next=true option while running the command.

To upgrade from one major angular version to another version, use the format ng update @angular/cli@^<major_version> @angular/core@^<major_version>.
