[github] How to move 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?

This question is related to github bitbucket

The answer is


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.

It looks like:

I realize this is an old question. I found it 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:

# 3. Find the team name, and grabulate the Team ID

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.

  1. In the upper-right corner of any page, click , and then click Import repository.
  2. Under "Your old repository's clone URL", type the URL of the project you want to import.
  3. Choose your user account or an organization to own the repository, then type a name for the repository on GitHub.
  4. 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.
  5. Review the information you entered, then click Begin import.

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

  1. https://help.github.com/categories/importing-your-projects-to-github
  2. https://help.github.com/articles/importing-a-repository-with-github-importer/

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 [email protected]: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

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.


Here are the steps to move a private Git repository:

Step 1: Create Github repository

First, create a new private repository on Github.com. 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:

  1. Check out the existing repository from Bitbucket:
    $ git clone https://[email protected]/USER/PROJECT.git
  1. 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
  1. Push all branches (below: just master) and tags to the Github repository:
    $ git push upstream master
    $ git push --tags upstream

Step 3: Clean up 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:

  1. Double-check that the Github repository has all content

  2. Go to the web interface of the old Bitbucket repository

  3. Select menu option Setting > Delete repository

  4. Add the URL of the new Github repository as redirect URL

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


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

http://www.blackdogfoundry.com/blog/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. Simple and straight forward.

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

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

  1. directly open Github Importer and enter the url. It will look like: Screenshot of github importer
  2. give it a name (or it will import the name automatically)
  3. select Public or Private repo
  4. Click Begin Import

UPDATE: Recently, Github announced the ability to "Import repositories with large files"


It's very simple.

  1. Create a new empty repository in GitHub (without readme or license, you can add them later) and the following screen will show.

  2. In the import code option, paste your Bitbucket repo's URL and voilà!!

Click Import code


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:

  1. Go to https://github.com/settings/tokens and create an access token. We only need the "repo" scope.

  2. Save the move_me.sh script in a working folder and edit the file as needed.

  3. Don't forget to CHMOD 755

  4. Run! ./move_me.sh

  5. 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?

Checkout the developer guide, it's a couple of edits away.


Happy moving.
