how to convert svn repository to git on Windows

Question

We have remote svn repository and we want it to convert to git. Could you please tell me how is it possible to do it on Windows? Thank.

Answer 1

I ended up doing this so much, I made a batch script to help out:

usage: SvnToGit

Prerequisites

• You should already have the URL to the empty git remote repository.
• You should have a pre-existing authors.txt file at the root ready to go.

• Unless Git understands your svn format, you will need to run svnserve to 'serve' the repo. You can create a window service to do, something like this:

  c:>sc create svnserve binpath="\"svnserve.exe\" --service -r C:\Users\UserName\Repositories\Svn" displayname="Subversion Server" depend=Tcpip start=auto

Caveats:

• Check the intermediate results, occasionally something may fail
  (especially svn clone).
• Note the section for manual changes if needed for tags. Perhaps, this could be done in batch file, but it seemed complex and not a high priority for me. There is a PAUSE here, so
  you can make these changes manually.
• I have not tested this on many systems, you might need to tweak the script a bit to adjust to your system.

The actual batch file:

REM Argument 1: Path to your repository
REM Argument 2: Path to your new Git working directory
REM Create authors.txt file
REM It will contain lines like:
REM SomeCoder = Some Guy 
REM If Git is now aware of the format of svn repository, you will need to use svnserve:
REM svnserve -d -R --root path/to/your/repository
PAUSE

IF EXIST bare.git\NUL RD /S /Q bare.git
IF EXIST GitTemp\NUL RD /S /Q GitTemp

REM The following will not work, if SVN is using a newer FS than what Git is aware of
REM git svn clone file:///%1 --prefix=svn/ --no-metadata -A authors.txt --stdlayout GitTemp
REM So, use
git svn clone svn://localhost/%1 --prefix=svn/ --no-metadata -A authors.txt --stdlayout GitTemp
PAUSE

REM GitIgnore
cd GitTemp
git svn show-ignore > .gitignore
git add .gitignore
git commit -m "Convert svn:ignore properties to .gitignore."
cd ..

REM Bare Repo
git init --bare bare.git
cd bare.git
git symbolic-ref HEAD refs/heads/trunk
cd ..

cd GitTemp
git remote add bare ../bare.git
git config remote.bare.push 'refs/remotes/*:refs/heads/*'
git push bare master
cd ..

REM clean up SVN type stuff
cd bare.git
REM git branch -m trunk master
git branch -m svn/trunk master
git symbolic-ref HEAD refs/heads/master
cd ..

REM Manual changes if needed for tags
REM git for-each-ref --format='%(refname)' refs/heads/tags |
REM cut -d / -f 4 |
REM while read ref
REM do
REM   git tag "$ref" "refs/heads/tags/$ref";
REM   git branch -D "tags/$ref";
REM done
PAUSE

REM Working Directory
git clone bare.git %2

cd %2
git checkout master

git remote remove origin
PAUSE

git remote add origin %3
REM Then
git push -u origin master
