Transfer git repositories from GitLab to GitHub - can we, how to and pitfalls (if any)?

Question

Can one transfer repositories from GitLab to GitHub if the need be. If so, how exactly can I go about doing the same?

Also, are there any pitfalls in doing so or pre

Answer 1

I had the opposite problem and finally had to create my own bash shell script for the company to migrate the hundred of repos from Github to Gitlab due to a change in the company policy.
The script use the Gitlab API to remotely create a repo, and push the Github repo into it. There is no README.md file yet, but the sh is well documented.
The same thing can be done opposite way I imagine. Hope this could help.
