Pick a Component to Migrate

To decide whether to migrate a component, first understand how Aura components and web components work together, and then evaluate how and where the component is used.

Before you pick a component to migrate, make sure that you understand the concept of facets in Aura components.

Let’s review the most important facts about how Lightning web components and Aura components work together.

  • Lightning web components and Aura components can co-exist in the same runtime.
  • An Aura component can contain a Lightning web component.
  • A Lightning web component can’t contain an Aura component.
  • If an Aura component has facets that contain other Aura components, you must migrate those other Aura components too.
