Styleguide owners can transfer the ownership of their styleguides directly from the “Styleguides” tab by clicking on the settings icon that appears when you hover over it.
Transferring a personal styleguide to your Organization
If your team is on the Organization plan, you can transfer your personal styleguide to that organization from the “Styleguides” tab.
Hover over a styleguide under your “Personal Workspace”, click on the settings icon. You'll see the name of your organization after you click on the “Transfer Ownership” option.
☝️ You can only transfer a project if your role is Editor, Admin or Owner in the organization.
When you transfer a parent styleguide, all the child styleguides will also be transferred without losing their parent-child relationships.
