最近我不得不将几个Git存储库迁移到SVN上，在尝试了我能找到的所有解决方案之后，最后对我有用的是Mercurial(是的，使用了第三种VCS)。根据这份指南，我提出了以下流程(适用于Linux，但基本思路也适用于Windows)。

The necessary packages: $ sudo apt-get install git subversion mercurial python-subversion Mercurial needs to be configured by adding the following to ~/.hgrc: [extensions] hgext.convert= Create some temporary working directories (I had several repositories to migrate so I created directories for the SVN and Git versions, to keep them separate): $ mkdir svn $ mkdir git Make an empty local SVN repository: $ svnadmin create svn/project Clone the existing Git repository: $ git clone server/path/project.git git/project Let Mercurial do its thing: $ hg convert --dest-type svn git/project svn/project Now the SVN repository should contain the full commit history, but not with original timestamps. If this is not an issue, skip over the next part to step 11. With a little work, the date and time of each commit can be changed. Since my repositories are fairly small, it was feasible for me to do it manually. First, create a pre-revprop-change hook in the SVN repository with the following contents, to allow the necessary property to be modified: #!/bin/bash exit 0; This script has to be made executable: $ chmod +x svn/project/hooks/pre-revprop-change Mercurial created a working copy of the SVN repository, named project-wc, so switch to it and edit the commit times: $ cd project-wc $ svn propedit svn:date --revprop -r 1 Enter the correct date and time (pay attention to timezones!) and save. You should get a message saying "Set new value for property svn:date on revision 1". Now rinse and repeat for every other revision. Optionally check the commit history to make sure everything looks OK: $ svn log -r 1:HEAD Then go back up one level: $ cd .. Dump the repository: $ svnadmin dump svn/project > project.dump And load the dump on your Subversion server. Done!

这个过程可能也可以直接在远程存储库之间工作，但是我发现与本地存储库一起工作更容易。修正提交时间需要做很多工作，但总的来说，这个过程比我发现的任何其他方法都要简单得多。

我需要将现有的Git存储库提交到一个空的SVN存储库。

我是这样做到的:

$ git checkout master
$ git branch svn
$ git svn init -s --prefix=svn/ --username <user> https://path.to.repo.com/svn/project/
$ git checkout svn
$ git svn fetch
$ git reset --hard remotes/svn/trunk
$ git merge master
$ git svn dcommit

它毫无问题地运行着。我希望这能帮助到一些人。

因为我必须使用不同的用户名向SVN存储库授权(我的源使用私钥/公钥身份验证)，所以我必须使用——username属性。

还有一个有效的序列(每个步骤都有一些注释):

Install git-svn and subversion toolkits: sudo apt-get install git-svn subversion Switch inside the PROJECT_FOLDER cd PROJECT_FOLDER Create the project path on the Subversion server (unfortunately the current git-svn plugin has a defect in comparison with TortoiseSVN). It is unable to store source code directly into the PROJECT_FOLDER. Instead, by default, it will upload all the code into PROJECT_FOLDER/trunk. svn mkdir --parents protocol:///path/to/repo/PROJECT_FOLDER/trunk -m "creating git repo placeholder"

在这里，中继在路径的末端是强制性的

Initialize the git-svn plugin context inside the .git folder git svn init -s protocol:///path/to/repo/PROJECT_FOLDER This is the place where trunk at the end of the path is unnecessary Fetch an empty Subversion repository information git svn fetch This step is helping to synchronize the Subversion server with the git-svn plugin. This is the moment when git-svn plugin establishes remotes/origin path and associates it with the trunk subfolder on the server side. Rebase old Git commits happened before the git-svn plugin became involved in the process (this step is optional) git rebase origin/trunk Add new/modified files to commit (this step is regular for Git activities and is optional) git add . Commit freshly added files into the local Git repository (this step is optional and is only applicable if step 7 has been used): git commit -m "Importing Git repository" Pushing all the project changes history into the Subversion server: git svn dcommit

在Subversion存储库中为项目创建一个新目录。

# svn mkdir --parents svn://ip/path/project/trunk

切换到git管理的项目并初始化git-svn。

# git svn init svn://ip/path/project -s
# git svn fetch

这将创建一个单独的提交，因为您的SVN项目目录仍然为空。现在把所有东西都基于这个提交，git svn dcommit，你应该完成了。不过，这会严重打乱你的提交日期。

在我的例子中，我必须从SVN启动一个干净的项目

$ Project> git svn init protocol://path/to/repo -s
$ Project> git svn fetch

添加你所有的项目资源…

$ Project> git add .
$ Project> git commit -m "Importing project sources"
$ Project> git svn dcommit
