Our organization has a self hosted GitLab server. We want to migrate to GitHub.
Github.com's import (the one in the web app) won't work because our GitLab server is not reachable from the Internet.
After looking at some stack overflow questions it says to export the project from GitLab, but on our GitLab server there is no option to export. Is there any standard process or any way to migrate all our old repositories from GitLab self Hosted to Git-Hub? It must include all tags, commit messages and branches as they exit in Git-Lab.
Any suggessions will really appreciated, Thank you.
