Documenting my process:

• Follow the steps from https://angular.dev/update-guide?v=16.0-18.0&l=3. Encountering tons of packages dependencies errors. Impossible to move on.
• Research how to upgrade from Angular 16 to 17 (Angular must be upgraded one version at the time)
• The sources mostly helped me to understand how to move on: https://dev.to/nikosanif/angular-authentication-upgrade-to-angular-18-382h https://ihsanulpro.medium.com/upgrade-to-angular-15-angular-14-to-angular-15-application-migration-cb74cfcba129
• Using ng update and npx npm-check-updates -u to check packages that needs to be updated and their latest version.

Command history to upgrade so far:

• ng update @angular/core@17 @angular/cli@17 --force
