git push all branches from one remote to another remote

Question

I have two remote: upstream and origin. upstream is something I can't push to. origin is my own repo. How can I fetch all branches from upstream and then push them to origin? I tried:

git fetch upstream git push --all origin 

But it doesn't work.

Answer 1

You may want to try cloning your upstream repo with --mirror option and then push to your new remote with --mirror option too

You'll have the following flow:

git clone <upstream-repo-url/repo.git> --mirror cd <repo> git remote add <your-remote-name> <your-remote-url/repo.git> git push <your-remote-name> --mirror 

⚠ Be really careful with the push --mirror as it will delete branches that are on your <your-remote-name>

Answer 2

I just needed to copy one repository from Bitbucket to GitHub, these are the steps assuming your remote is called origin, all branches and tags will be copied:

git remote add neworigin url-to-new-remote git push neworigin --tags "refs/remotes/origin/*:refs/heads/*" 

Good thing about this is that files in your working copy won't be modified.
