I ended up taking over a Vue 1.x codebase and tried to update it to vue2. We used single file components and it was a nightmare trying to upgrade. I spent a good two weeks trying to upgrade and eventually just stopped because it was just taking too long. There were a lot of breaking changes from 2.0 to 1.0, especially with the way events were handled. Now, I will admit that the person who wrote the vue 1.x version did not write idiomatic vue and that caused some problems in updating. A lot of the components we used were also not updated to vue 2.0 and, of course, they were using deprecated features. That meant I had to search for something similar to replicate the existing functionality.
