A role can be expanded into a circle through governance, or turned back into a role in a similar way.
This article shows how to take a sub circle and turn it back into a role, while simultaneously preserving a role within that circle and moving it up to its parent circle.
In this example we'll be collapsing the circle called "Website" back into a role in its parent circle "Market Place":
- Open a governance meeting and choose "Add/Edit Role" and select "Website" (See: How do I start a governance meeting?)

- In the resulting proposal: 1) Tick "Remove this circle", 2) Select "Keep Website as a role in Market Place" (otherwise the circle and all roles within it would be deleted), and 3) Select the roles to be retained (allowing unselected ones to be deleted).
