By understanding package dependencies and how they interact with your project's ecosystem, you can effectively handle updates with minimal disruption. Whether you choose to upgrade your schematics directly or remove and reinstall packages, both solutions will set you on the right path to successfully moving from Angular 13 to 14.

If you encounter any issues during the process, don't hesitate to seek assistance from the extensive Angular community or refer to the official Angular documentation.
