How to Upgrade from Angular 16 to Angular 17?

Today, I'll demonstrate the process of upgrading from Angular 16 to Angular 17. This article provides a comprehensive guide on the Angular version 17 upgrade. The tutorial offers a straightforward example of transitioning from @angular 16 to 17, specifically focusing on updating Angular CLI to version 17 in an Ubuntu environment. Follow the steps outlined below to successfully upgrade your Angular application.

While working on my Angular project, I encountered the need to migrate from Angular 16 to Angular 17. Attempting to execute a straightforward update command proved unsuccessful, indicating that certain configurations were impacted. This prompted me to consider alternative methods for upgrading Angular.

There are two approaches to facilitate the transition from Angular 16 to 17. Initially, we'll attempt a direct update of the Angular CLI version. If this proves ineffective, an alternative solution involves uninstalling and reinstalling the Angular CLI, following the provided steps.

Following Way to Upgrade Angular 16 to 17 Version

• Way 1: Update Angular CLI
• Way 2: Update Angular CLI using reinstall

Let's see both ways:

Way 1: Update Angular CLI
