[question] is that possible Vaadin 7 + Vaadin Newest version coexist?

i have one legacy system that based on Vaadin 7 and cannot upgrade to newest version . but new requirement needs Vaadin newest feature . i am asking is that possible we import new Vaadin lib into the Vaadin 7 dependency . even more i am thinking if the new vaadin component can call vaadin 7 component . thank you

You can use the Elements add-on: https://vaadin.com/directory/component/elements-add-on to use web components in a Vaadin 7 or Vaadin 8 application. This means you can use a JavaScript web component like vaadin-text-field, but you’ll need to implement the Java API entirely yourself. In the opposite direction, you can use Vaadin 7 components (including entire views) in a Vaadin 14 application with Multiplatform Runtime: https://vaadin.com/multiplatform-runtime

thank you, that’s good suggestion
