A Developer's Tale: Migrating an Angular app from version 10 to 18
summary
Real-world migration of the Devoxx CFP app from Angular 10 to 18 covers stepwise upgrades one major version at a time, using Node version managers (NVM/ASDF), ng update schematics, and commands like npm ls --all and npm outdated to map dependency pain points. Concrete problems include ngx-translate blocking 13.2, missing components copied into-repo, mismatched PostCSS versions fixed with npm dedupe, and occasional --force installs. The 10→17 run takes ~15–20 days (~2 days/version); later upgrades drop to hours.
