Extjs 6 what are the differences Modern | classic?

Question

JavaScript

I have a site on extjs 6 classic toolkit, I need to migrate it to modern for phones. My steps are:
1. from app/view folder -> move files to classlic/src/view
2. write new views for and put them in modern/src/view
making the first point, I ran into a problem, application.js for two versions (classic and modern) one. and classic requires require Ext.plugin.Viewport which is not present in modern toolkit. How to solve this problem?

Answer 1

As far as I understand the sequence of actions: copy the entire classic to modern and then replace the classic widgets with modern analogues. Somehow I see it myself. Although he himself has not yet migrated, but in the plans.
