We have implemented the frontend API of Angular.js using the latest Angular. But the templates some differences <https://angular.io/guide/ajs-quick-reference> between Angular.js and Angular. So to help users migrate templates, we provide a migration tool that will be integrated into the Zeppelin web. This is its DEMO <https://ng1-updater.hsuan.xyz/> it can quickly fix these differences. We plan to do the following work: 1. Add a new type "%ng" (official abbreviation) to distinguish between Angular.js and Angular templates. 2. When the user runs a paragraph with the "%angular" type, the upgrade dialog will be open. 3. Upgrade the template in the dialog and click the "Update and Copy" button. 4. Automatically create a paragraph of the type "%ng" template below.
