Vaadin 7 App migration

We have a vaadin 7 based web app that needs to be migrated to the latest LTS Vaadin version, 14.8.3.

The migration will consist of...

Rewriting 13 view classes

Rewrite containers to data providers

CSV/PDF generation

Navigation -> Routes

Migrate shell for application and 8 views

[login to view URL] Add-on charts (mostly line, doughnut, gauge)


Lists of cards

Tables (filters, sorting, no column picker afaik)


Windows (dialogs)


Embedded videos

Menus (MenuBars)

Expandable cards


Possible other add-ons

Convert customized Valo theme

Make application work well on mobile

Even more responsive

To start we would like for you to migrate the necessary objects to have just a working main page. The main page consists of a ui class and a single view class with ui elements like drop downs, panels, and [login to view URL] charts. Integration with Okta Oauth is also required.

If your initial work is satisfactory you will move on to the remaining 12 views. Migration for the the backend is not anticipated.
