I have 1.2 version of WAB running and I am trying to upgrade to 2.4.
command to upgrade a single app
node_x64 upgrade <older WAB install directory> <appid>
works fine and process shows upgrade successful.
But when I launch 2.4 WAB and go to the builder for the test application I am trying to convert, I get config.json errors for bunch of widgets. In my test application , all widgets are standard widgets.
Is it possible to directly go from 1.2 to 2.4 ?
