How do I transition a repository from GitLab to GitHub?
Inside your GitHub organization, create an empty private repo with the same name as the GitLab repo that you want to transfer. On your local copy of the GitLab repository, navigate to the .git/config file and find the lines that look similar to the following:
url = email@example.com:team-name/repo-name.git
fetch = +refs/heads/*:refs/remotes/origin/*
Replace the original url with your new GitHub repo url, either in HTTPS or SSH format. Do a git push: "git push --all". All code and commit history will be pushed to the new GitHub repository. You can then archive the GitLab repo to make it read-only.
