title: GitLab merge request into GitHub?
body: <p>My code is on GitHub, but I use GitLab CI. I set up GitLab CI/CD external repo and linked my GitHub. I set up GitLab Pull mirroring to get changes from my GitHub.</p>
  
  <p>Since my CI is on GitLab, I am working on setting up review deployments and automated merge requests here. </p>
  
  <p>Is it possible/appropriate to handle merge requests on GitLab, then persist to GitHub? Do I just need to set up a Push mirror from GitLab to GitHub?</p>
