  1. Install SubGit tool according to the Installation guide.

  2. Configure GitHub


    • login to GitHub and create a new repository:
       

  3. Configure the local repository:


    • Run this command on behalf of the same user you use to serve Git repository:

      > subgit.bat configure --layout auto --trunk TRUNK SVN_URL GIT_REPO


      where

      • SVN_URL    – URL to the SVN project.
      • GIT_REPO  – a path to the new Git repository where data from the SVN project will be imported to.
      • TRUNK        –  a path, relative to SVN_URL, that leads to an SVN directory that plays a role of the main line of development.

      •  see the configuration command example.
        subgit configure example
        > subgit.bat configure --layout auto --trunk trunk http://example.com/svn/repository/project C:\repo.git
        
                    SubGit version 3.2.4 ('Bobique') build #3670
        
                    Configuring writable Git mirror of remote Subversion repository:
                        Subversion repository URL : http://example.com/svn/repository/project
                        Git repository location   : C:\repo.git
        
                    Detecting peg location...
                    Authentication realm: <http://example.com:80> Subversion Repository
                    Username [user]: user
                    Password for 'user':
                    Peg location detected: r10248 project/trunk
                    Fetching SVN history... Done.
                    Growing trees... Done.
                    Project origin detected: r1 project/trunk

                    CONFIGURATION SUCCESSFUL
        
                    To complete SubGit installation do the following:
        
                    1) Adjust Subversion to Git branches mapping if necessary:
                        C:\repo.git\subgit\config
                    2) Define at least one Subversion credentials in default SubGit passwd file at:
                        C:\repo.git\subgit\passwd
                       OR configure SSH or SSL credentials in the [auth] section of:
                        C:\repo.git\subgit\config
                    3) Optionally, add custom authors mapping to the authors.txt file(s) at:
                        C:\repo.git\subgit\authors.txt
                    4) Run SubGit 'install' command:
                        subgit install "C:\repo.git"
    • Specify authors mapping

      Configure authors mapping in default authors mapping file:

      GIT_REPOS/subgit/authors.txt 

      Or change core.authors option so that it points to the global authors mapping file.

      Find more details about authors mapping in Authors mapping article.



  4. Import data to the local Git repository

    > subgit import GIT_REPO
     See subgit import example…
    subgit import
    > subgit import C:\repo.git
         SubGit version 3.2.4 ('Bobique') build #3670
    
         Authentication realm: <http://svn.example.com:80> Subversion Repository
          Username [git]: user
          Password for 'user': 
    
          Translating Subversion revisions to Git commits...
    
             Subversion revisions translated: 10248.
             Total time: 2 hours 15 minutes 38 seconds.
    
          IMPORT SUCCESSFUL
  5. Sync the local Git repository with GitHub

    • navigate to the newly created local Git repository 

      > cd GIT_REPO
    • add a remote to the local Git repository:

      > git remote add github GITHUB_REPO

      where 

      • GITHUB_REPO – GitHub project URL.


    • push local repository content into GitHub repository:

       See git push command…
      git push
      > git push github --all --follow-tags
    • When the command is completed, the local repository is not needed anymore and can be removed:

      > rmdir /S /Q GIT_REPO
  6. Clone your GitHub repository and start to work with it

    > git clone GITHUB_REPO WORK_TREE

    where

    • WORK_TREE – a path to your working copy.
    • GITHUB_REPO – GitHub project URL
     See git clone example
    git clone example
    > git clone https://github.com/user/project.git ./project.git
         Cloning into './project.git'...
         Password for 'http://user@example.com': 
         remote: Counting objects: 99, done.
         remote: Compressing objects: 100% (39/39), done.
         remote: Total 99 (delta 50), reused 99 (delta 50)
         Unpacking objects: 100% (99/99), done.

    Empty working tree case

    If Git warns you that you are cloning an empty repository and you don't see your files in the working tree, most probably automatic branches and tags mapping didn't work correctly. In this case, mapping has to be set manually, see details on mapping in Branches and tags mapping.

  7. Get support.

    If you have encountered any problems, see the following guides for more details:

    Note:

    For one-time import, no license is needed.
