Now admins can transfer and rename a repository at the same time. Before, each action was separate.
In the transfer repository screen, choose “Select one of my organizations”. The “Repository name” field will appear below. You must be an admin on the target organization to rename the repository. Renaming isn’t available if you “Specify an organization or username”.
Optionally change the name the repository will have after transferring. Then complete the transfer!
