GitHub doesn't provide you with any standard way to migrate the related metadata, but unlike Atlassian's Bitbucket, which doesn't make everything accessible with their APIs, it's possible to get all the data with GitHub's API (as of today). If you use GitLab importer tool, we migrate everything from your old project. All issues, all pull requests, and we even migrate inline comments inside a pull request. All it takes is one OAuth authorization and the pressing of a button. When inside GitLab, we even give you an Export zip file, that you can import in your hosted version of GitLab (or use any alternative, that can read our export file format).
