How can I move a Git repository with all branches from Bitbucket to GitHub?

What is the best way to move a Git repository with all branches and full history from Bitbucket to GitHub?

Is there a script or a list of commands I have to use?

Github provide tools and documentation for that: help.github.com/articles/… help.github.com/articles/…
Little late to the party but here is a script for migration: gist.github.com/chinmaya-n/cff02f1277c811deab2e550f2aad9967

It's very simple.

Create a new empty repository in GitHub (without a README or license, you can add them later) and the following screen will show. In the import code option, paste your Bitbucket repository's URL and voilà!!

You're really answering the question here, as the accepted answer shows only a generic Git related method. Your answer is way simpler!
This answer is good as long as you are the one creating the repository and it is bare. If someone else has created the repository for you (like the admin incharge of branch creation) then this doesn't work. Accepted answer is the way to go in such a case.
Heads up for anyone else thinking about using this method, remove your two-factor authentication on your previous repository host before you use this service, otherwise you'll be stuck in an endless loop of trying to remove the newly created repository in GitHub, and the only way to get out of that is to replace the /import on the end of the URL with /settings to access the settings and remove it.
Small caveat- if you run into an issue you won't get a descriptive error message.
Using GH's "Import repository" feature is the right choice 95% of the time. However, if it fails, it doesn't give helpful error messages and you must contact GH support. I couldn't use it for one repo because it contained a large file (>100MB). I needed to use the accepted CLI method, removing the large file just before pushing the repo to GH.

You can refer to the GitHub page "Duplicating a repository"

It uses:

git clone --mirror: to clone every references (commits, tags, branches)

git push --mirror: to push everything

That would give:

git clone --mirror https://bitbucket.org/exampleuser/repository-to-mirror.git
# Make a bare mirrored clone of the repository

cd repository-to-mirror.git
git remote set-url --push origin https://github.com/exampleuser/mirrored
# Set the push location to your mirror

git push --mirror

As Noted in the comments by L S:

it is easier to use the Import Code feature from GitHub described by MarMass. See https://github.com/new/import

Unless... your repo includes a large file: the problem is, the import tool will fail without a clear error message. Only GitHub Support would be able to diagnose what happened.


This method created a problem for me (not sure if it is problem). When I mirrored the repo from bitbucket to github then for 5 branches it is shown as "Compare and Pull Request" in github. It is not shown as branches in github. What can I do about it?
And then what about issues and wikis?
@FractalizeR wiki is just another repo, that you can replicate as well (github.com/blog/699-making-github-more-open-git-backed-wikis). There is no easy way to replicate issues though. You need to use the Api (various GitHub repo backup programs do just that: addyosmani.com/blog/backing-up-a-github-account)
This works if you want to move a repository from Github to Bitbucket as well.
I needed to use the this method to copy a repo because it contained a large file (>100MB). GH wouldn't allow large files in their repos. I removed the large file before pushing the repo to GH. However, barring other problems, using GH's "Import repository" feature is the right choice 95% of the time, as described in another answer. However, if it fails, it doesn't give helpful error messages and you must contact GH support. It was GH support that informed me of the file size restriction.

In case you couldn't find the "Import code" button on GitHub, you can:

Directly open GitHub Importer and enter the URL. It will look like: Give it a name (or it will import the name automatically) Select Public or Private repository Click Begin Import

In May 2016, GitHub announced the ability to "Import repositories with large files".


Unfortunately this didn't work for my attempt at moving from codebasehq to git-hub, gave an "This URL is not supported". :(
@sjmcdowall Sorry it didn't but I believe it should have worked since the codebasehq URL points to a git repository.
URL no longer exists.
@CodedContainer I just checked and it works. I even updated the screen shot just now.
The url will only return a 404 if you are not logged into GitHub. If you are logged in, the import tool will load.

Se Moving Repository from Bitbucket to GitHub.

This helped me move from one Git provider to another. At the end of it, all the commits were in the destination Git repository. Simple and straightforward.

git remote rename origin bitbucket git remote add origin https://github.com/edwardaux/Pipelines.git git push origin master Once I was happy that the push had been successful to GitHub, I could delete the old remote by issuing: git remote rm bitbucket


Please include the relevant parts of a link in your answer as it should be able to stand on its own.
I get an error that says "Error: failed to push som refs to 'url.gi' hint: updates were rejected because the remote contains work that you do not have locally. This is usually caused by another repository pushing to the same ref. You may want to first integrate the remote changes (eg pull...) before pushing again. See the note about fast-forwards in git push --help for details.
this is the only answer that is still working in 3/3/2019 :)

I had the reverse use case of importing an existing repository from GitHub to Bitbucket.

Bitbucket offers an Import tool as well. The only necessary step is to add URL to repository.

I found this question several months ago when I was trying to do the same thing, and was underwhelmed by the answers given. They all seemed to deal with importing from Bitbucket to GitHub one repository at a time, either via commands issued à la carte, or via the GitHub importer.

I grabulated the code from a GitHub project called gitter and modified it to suite my needs.

You can fork the gist, or take the code from here:

There is the Importing a repository with GitHub Importer

If you have a project hosted on another version control system as Mercurial, you can automatically import it to GitHub using the GitHub Importer tool.

In the upper-right corner of any page, click, and then click Import repository. Under "Your old repository's clone URL", type the URL of the project you want to import. Choose your user account or an organization to own the repository, then type a name for the repository on GitHub. Specify whether the new repository should be public or private.

Public repositories are visible to any user on GitHub, so you can benefit from GitHub's collaborative community.

Public or private repository radio buttonsPrivate repositories are only available to the repository owner, as well as any collaborators you choose to share with.

Review the information you entered, then click Begin import.

You'll receive an email when the repository has been completely imported.

In case you want to move your local Git repository to another upstream, you can also do this:

To get the current remote URL:

git remote get-url origin

will show something like: https://bitbucket.com/git/myrepo

To set new remote repository:

git remote set-url origin git@github.com:folder/myrepo.git

now push contents of current (develop) branch:

git push --set-upstream origin develop

You now have a full copy of the branch in the new remote.

Optionally, return to original git-remote for this local folder:

git remote set-url origin https://bitbucket.com/git/myrepo

It gives the benefit you can now get your new Git repository from GitHub in another folder so that you have two local folders both pointing to the different remotes, the previous (Bitbucket) and the new one both available.

I made the following Bash script in order to clone all of my Bitbucket (user) repositories to GitHub as private repositories.

Requirements:

jq (command-line JSON processor) | macOS: brew install jq

Steps:

Go to Personal access tokens and create an access token. We only need the "repo" scope. Save the move_me.sh script in a working folder and edit the file as needed. Don't forget to chmod 755 Run! ./move_me.sh Enjoy the time you have saved.

Notes:

It will clone the Bitbucket repositories inside the directory the script resides (your working directory).

This script does not delete your Bitbucket repositories.

Need to move to public repositories on GitHub?

Find and change the "private": true to "private": false below.

Moving an organization's repositories?

Check out the developer guide. It's a couple of edits away.

Happy moving.

Here are the steps to move a private Git repository:

Step 1: Create a GitHub repository

First, create a new private repository on GitHub. It’s important to keep the repository empty, e.g., don’t check option Initialize this repository with a README when creating the repository.

Step 2: Move existing content

Next, we need to fill the GitHub repository with the content from our Bitbucket repository:

Check out the existing repository from Bitbucket: git clone https://USER@bitbucket.org/USER/PROJECT.git Add the new GitHub repository as upstream remote of the repository checked out from Bitbucket: cd PROJECT git remote add upstream https://github.com:USER/PROJECT.git Push all branches (below: just master) and tags to the GitHub repository: git push upstream master git push --tags upstream

Step 3: Clean up the old repository

Finally, we need to ensure that developers don’t get confused by having two repositories for the same project. Here is how to delete the Bitbucket repository:

Double-check that the GitHub repository has all content Go to the web interface of the old Bitbucket repository Select menu option Setting → Delete repository Add the URL of the new GitHub repository as the redirect URL

With that, the repository completely settled into its new home at GitHub. Let all the developers know!

Peter Mortensen

The simplest way of doing it:

git remote rename origin repo_bitbucket

git remote add origin https://github.com/abc/repo.git

git push origin master

Once the push to GitHub is successful, delete the old remote by running:

git remote rm repo_bitbucket
