Migration
These APIs help you move projects to or from GitHub.
Organization migrations
The organization migrations API lets you move a repository from GitHub to GitHub Enterprise Server.
Source imports
The Source Import API lets you start an import from a Git, Subversion, Mercurial, or Team Foundation Server source repository. This is the same functionality as the GitHub Importer.
User migrations
You can use this API to review, backup, or migrate your user data stored on GitHub.com.
