Migration from svn to git

Create a users file (i.e. users.txt) for mapping SVN users to GIT:

user1 = First Last Name <email@address.com>
user2 = First Last Name <email@address.com>
...

SVN will stop if it finds a missing SVN user not in the file. But after that you can update the file and pick-up where you left off.

Now pull the SVN data from the repo:

git svn clone --stdlayout --no-metadata -A users.txt svn://hostname/path dest_dir-tmp

This command will create a new git repo in dest_dir-tmp and start pulling the SVN repo. Note that the "--stdlayout" flag implies you have the common "trunk/branches/tags" svn layout.

If a user name is not found, update your users.txt file then:

cd dest_dir-tmp
git svn fetch

When completed, git will checkout the SVN trunk into a new branch. Any other branches are setup as remotes. You can view the other SVN branches with:

git branch -r

If you want to keep other remote branches in your repo, you want to create a local branch for each one manually. If you don't do this, the branches won't get cloned in the final step.

git checkout -b local_branch remote_branch
# it's ok if local_branch and remote_branch are the same name

Tags are imported as branches. You have to create a local branch, make a tag and delete the branch to have them as tags in git. To do it with tag "v1":

git checkout -b tag_v1 remotes/tags/v1
git checkout master
git tag v1 tag_v1
git branch -D tag_v1

Clone your GIT-SVN repo into a clean git repo:

git clone dest_dir-tmp dest_dir
rm -rf dest_dir-tmp

Finally, remove the remote from your clean git repo that points to the now deleted temp repo:

git remote rm origin
