I just mirrored a github repo.
Like this:
git clone --bare git@github.oldproject/oldproject.git
cd oldproject.git
git push --mirror git@github.com:newproject/newproject.git
This works great but closed issues and pull requests are not transfered?
Is this possible?
Pull requests and issues are not part of git. They are features of the GitHub or other tools.
If you wish to checkout pull request locally follow those instructions:
