I have bare cloned a public github repository(say projectA) and created a private github repository (say projectAPrivate), then mirror pushed the cloned projectA to projectAPrivate(as outlined here https://help.github.com/articles/duplicating-a-repository
git clone --bare https://github.com/exampleuser/old-repository.git
# Make a bare clone of the repository
cd old-repository.git
git push --mirror https://github.com/exampleuser/new-repository.git
# Mirror-push to the new repository
cd ..
rm -rf old-repository.git
# Remove our temporary local repository
)
Since then, I have pushed changes to projectAPrivate, now projectA has released new versions. How do I have pull/merge changes from the public projectA repository to my private github project projectAPrivate.
