Migration to Vaadin 14 from Vaadin 7 Portlets

Has there been any tests for Vaadin 7 portlet using IPC able to communicate to a an embedded Vaadin 14 web component? I am looking for a gradual migration path away from portlets to using Vaadin 14 embedded components with inter-component communication. I don’t know if the client side IPC supported between Vaadin portlets is interoperable with inter-component communication used in Vaadin 14. Thanks.
