To give your migration a head start; Chris Fitz (a member of the Vue core team) created a little helper app that will scan your code and guide you in the migration:
- Install Vue Migration Helper with the following npm command:
npm install -g git://github.com/vuejs/vue-migration-helper.git
- Navigate to your app folder.
- Run the program with the following command:
vue-migration-helper
All the lines in which a change is necessary will be highlighted. Once you are finished updating, or if you still have doubts, you should take a look at the official documentation migration page at https://rc.vuejs.org/guide/migration.html.
