下面是移动私有Git存储库的步骤:

步骤1:创建一个GitHub存储库

首先，在GitHub上创建一个新的私有存储库。保持存储库为空是很重要的，例如，在创建存储库时，不要勾选“使用README初始化这个存储库”选项。

步骤2:移动现有内容

接下来，我们需要用Bitbucket存储库中的内容填充GitHub存储库:

从Bitbucket中查看现有的存储库: git克隆https://USER@bitbucket.org/USER/PROJECT.git 添加新的GitHub存储库作为Bitbucket签出的存储库的上游远程: cd项目 git远程添加upstream https://github.com:USER/PROJECT.git 将所有分支(下面:只是master)和标签推到GitHub 存储库: Git推送上游master Git推——标签上游

步骤3:清理旧的存储库

最后，我们需要确保开发人员不会因为同一个项目有两个存储库而感到困惑。下面是删除Bitbucket存储库的方法:

仔细检查GitHub存储库是否包含所有内容 转到旧Bitbucket存储库的web界面 选择菜单项“设置→删除存储库” 添加新的GitHub存储库的URL作为重定向URL

这样，存储库就完全安顿在了GitHub的新家。让所有开发人员知道!

这很简单。

在GitHub中创建一个新的空存储库(没有README或许可证，您可以稍后添加它们)，将显示以下屏幕。 在import code选项中，粘贴你的Bitbucket存储库的URL和voilà!!

如果你在GitHub上找不到“导入代码”按钮，你可以:

直接打开GitHub Importer并输入URL。它看起来像: 给它一个名字(或者它会自动导入这个名字) 选择Public或Private存储库 单击“开始导入”

2016年5月，GitHub宣布能够“导入带有大文件的存储库”。

根据@MarMass的回答，如果GitHub导入器不断将你重定向到身份验证屏幕，你需要在BitBucket中创建一个应用程序密码，以便导入你的私有存储库:

去Bitbucket >个人设置>应用程序密码。 创建具有存储库读访问权限的应用程序密码。 当在GitHub导入器中提示输入您的用户名/密码时，输入您的BitBucket用户名，并将上面创建的令牌作为密码。

在设法解决身份验证问题后，我的导入也出现了以下消息:“有一个错误将提交推到GitHub.”。

这里的问题是，至少对我来说，我的GitHub帐户被设置为“阻止暴露我的电子邮件的命令行推送”，而我试图从Bitbucket导入的存储库包含来自我个人电子邮件地址的提交。在暂时禁用这个设置(GitHub >设置>电子邮件)后，我就可以去了。

我做了下面的Bash脚本，以克隆我所有的Bitbucket(用户)存储库到GitHub作为私有存储库。

要求:

jq(命令行JSON处理器)| macOS: brew install jq

步骤:

转到个人访问令牌并创建一个访问令牌。我们只需要“回购”范围。 将move_me.sh脚本保存在工作文件夹中，并根据需要编辑该文件。 别忘了chmod 755 快跑!。/ move_me.sh 享受你节省下来的时间吧。

注:

它会在脚本所在的目录(你的工作目录)中克隆Bitbucket存储库。 这个脚本不会删除你的Bitbucket存储库。

需要转移到GitHub上的公共存储库?

找到并更改下面的“private”:true为“private”:false。

移动组织的存储库?

请查看开发人员指南。还需要几次编辑。

快乐的运动。

  echo
  git push --mirror "git@github.com:$GH_USERNAME/$slug.git"
  j=$(( $j + 1 ))
  hr
  cd ..
  done
  i=$(( $i + 1 ))
done

几个月前，当我试图做同样的事情时，我发现了这个问题，并对给出的答案印象不深。他们似乎都在处理从Bitbucket一次一个存储库导入到GitHub的问题，要么是通过命令à点菜，要么是通过GitHub导入器。

我从一个名为gitter的GitHub项目中抓取了代码，并对其进行了修改以满足我的需求。

你可以分叉要点，或者从这里取代码:

# execute the script, iterating over your list
