This is a very high-risk upgrade, spanning four major versions (v16, v17, v18, v19) with multiple fundamental breaking changes. This is not a simple update and will require significant refactoring and testing.

Key Breaking Changes:

• Environment: Requires Node.js 18.13.0+ and TypeScript 5.2+. [3, 15]
• View Engine Incompatibility: As of v16, the Angular Compatibility Compiler (ngcc) is removed. Any third-party libraries still using the legacy View Engine will no longer work and must be updated or replaced. [3, 5, 6]
• New Template Syntax: v17 introduced a new built-in control flow (@if, @for, @defer) that replaces older structural directives like *ngIf and *ngFor. [9, 11]
• Architectural Shift: The ecosystem has moved to Standalone Components, Directives, and Pipes as the default, deprecating the reliance on NgModules. [2, 13] Additionally, a new Signal-based reactivity model has been introduced, paving the way for future zoneless applications. [4, 7]

Recommendation: This upgrade should be treated as a major project. Do not merge without a dedicated migration plan. Use the official ng update command incrementally (15->16, 16->17, etc.) to apply automated schematics and address breaking changes at each step.
