This is a massive upgrade, jumping 6 major versions from 13 to 19. It includes numerous significant breaking changes and fundamental shifts in the Angular framework that will require substantial code and architecture modifications.

Key Breaking Changes:

• Architectural Shift: The framework has moved from NgModule-based applications to Standalone Components, which became stable in v15 and are the default in v19. [1, 17, 29] This requires a new way of structuring applications.
• New Reactivity Model: Signals, a new system for managing state and change detection, were introduced in v16 and stabilized in v17. [12, 21] This is a major change from the traditional Zone.js-based approach.
• Tooling and Compatibility: Support for libraries built with the older View Engine was removed in v16 with the deletion of the Angular Compatibility Compiler (ngcc). [5, 15, 16] There are also strict new version requirements for Node.js and TypeScript with each major release. [5, 28]

Recommendation: A direct upgrade is not feasible. A sequential, version-by-version migration using the ng update command is mandatory to handle the numerous breaking changes. [6, 7, 35] This is a major refactoring effort that must be handled with significant planning and testing.
