You can keep your Ember application up-to-date with a few simple steps.
One of the most important that always follow and read the blog posts about the new version on Ember.js website.
My strategy is quite simple. I would like to know which packages are changed. Outside of the active project, I update ember-cli, and I create a new dummy app, so I can compare the version numbers and every type of changes between the new dummy app and my older active project.
Outside your older ember app folder:
$ cd ~ $ npm install -g ember-cli
Check your ember-cli version (outside of your project folder).
$ cd ~ $ ember -v
You should see the latest version.
Create a new dummy ember application
So we can compare packages in
$ cd ~/projects/temp $ ember new my-latest-app
Upgrade version numbers in your old project to match with the new dummy app.
package.json align the version numbers in your old project to match with the new defaults. (Update ember-cli, ember, ember-data, etc.) It is time to double check your other packages, like sass or firebase, etc. packages also, maybe there are an updated version which is compatible with the new Ember.
For avoiding package conflicts the most safest solution if you just remove these folders and reinstall all your packages.
$ cd my-updated-project $ rm -rf bower_components node_modules $ npm install && bower install
Good luck! :)
