You can import your existing GitHub Enterprise projects to GitLab Enterprise Edition only. You'd need to follow these same steps, but you'd also need to [enable GitHub Enterprise support](http://doc.gitlab.com/ee/integration/github.html) on your GitLab EE instance.
* Click on the "Import project from GitHub" link and you will be redirected to GitHub for permission to access your projects. After accepting, you'll be automatically redirected to the importer.

* To import a project, you can simple click "Add". The importer will import your repository and issues. Once the importer is done, a new GitLab project will be created with your imported data.
