# Step 2 - Removing legacy Servlets

The MPR framework manages the VaadinServlets to make sure the correct requests are routed to the right frameworks (either Flow or Vaadin 7/8). For that to work properly, all legacy VaadinServlets need to be removed. If you need some custom functionality, you can use the VaadinServlet provided by Flow instead.

See [Flow documentation on Dynamic content](https://vaadin.com/docs/v14/flow/advanced/tutorial-dynamic-content#using-custom-servlet-and-request-parameters) for details.
