How to migrate a Bitbucket repository to Github?

Question

I want to migrate an old Bitbucket repository, containing multiple branches, to Github. To accomplish this, I've followed this description:

# add remote github repository
$ git remote add upstream https://github.com:USER/PROJECT.git
# push all branches <-- doesn't work
$ git push upstream master
$ git push --tags upstream

Only the master branch is pushed to the Github repository (also for git push --all upstream ).

In order to push all branches to Github, I need to checkout them individually and do git push upstream .

How can I push all branches to Github without first checkout them?

Answer 2

Follow the below steps.

1. Mirror the source repo.

   git clone --mirror https://url-of-the-source-git-repo.git

2. Go to the newly cloned repo

   cd to-your-git-repo-folder.git

3. set the new remote url.

   git remote set-url --push origin https://url-of-the-destination-git-repo.git

4. Push to the new repo

   git push --mirror

By following these commands you will migrate to new repo with all the branches and commits.

Answer 3

First make sure that you have fetched all branches .

git fetch --all

Then push all branches to the new remote

git push upstream --all
