Requirement had no matching files (Ext.data.UuidGenerator) – myapp/app/model/MyModel:5:7 Look in the API Docs, and see: Ext.data.UuidGenerator is deprecated, ! use Ext.data.identifier.Uuid instead.! ! • root in the Proxy reader is deprecated. Use rootProperty instead.! ! • Ext JS 6 Stores don’t automatically set the storeId to the name of the class! ! ! 72! Simple migration!
• When you generate a new project, the microloader expects the new viewport is: ! app/view/main/Main.js! ! Therefore, your browser errors this:!

• Charts in Ext JS 6 are packages. You can choose to take the legacy SVG charts or the modern Canvas charts. When you see this error:! ! [ERR] com.sencha.exceptions.ExNotFound: Unknown definition for dependency : Ext.chart.Chart ! Use this fix in app.json:! "requires": [ "charts" //ext-charts for legacy charts ], 74! Simple migration!
No longer you need to define every field in the fields array! • You retrieve the data from a feed! • You set fields, only for data conversion! 75! Simple migration!
in the Controller is deprecated. Use onLaunch() instead! ! • Pictos icons are replaced by FontAwesome, you can set it like this:! iconCls: ‘x-fa fa-cog’ ! • Sencha Touch validations are now called validators TIP: http://docs.sencha.com/extjs/6.0/api_diffs/600_modern_diff.html! 76! Simple migration!

"builds": { "desktopprofile": { "toolkit": "classic", "theme": "theme-triton“, }, "iphoneprofile": { "toolkit": "modern", "theme": "theme-cupertino", } },! Every profile can have a Toolkit and a Theme. You will need to create builds for every profile. sencha app build Universal app migration!
