# 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, all legacy VaadinServlets have to be removed. If you need some custom functionality, you can use the VaadinServlet provided by Flow instead.

The next step is [Converting legacy UIs](https://vaadin.com/docs/next/tools/mpr/introduction/3-legacy-uis.md).
