If you are in the process of converting a component from its UIC version to the Seeds version, we recommend the following:
Intentionally, not all components that currently exist in UIC will exist in the same format in Seeds. Some UIC components, like SubmitApplication, aren’t really components at all, but pieces of page content that have significant business logic. These were not brought over to Seeds in their current form.
We recommend rebuilding large sections like this within your application using Seeds atoms and molecules, like the Card, Heading, Link, and Icon components, and Seeds tokens, like spacing, color, and typography. You will retain more control over the details of your content, while still getting all the consistency, accessibility, and themability benefits of using Seeds components.
