Answer 1

I recommend using ember-cli-update to update your ember projects. Please check it out. It avoids user-mistakes while upgrading (no manual merges, etc. ...).

Answer 2

You could try to delete node_modules and run npm install again. It could a package in your package.json that ember serve can't find. Also check the releases it is not easy to upgrade from older version to the latest one, too many deprecations. Also if it si too old i suggest you to start over create again the ember app.
