I'm about to migrate my SVN repo to GIT. I'm going to use svn2git which uses the git-svn.
Is there any way the process modifies the SVN repo? Since obviously this is very sensitive to change, I want to be sure that the original SVN will not be affected in any way.
git-svn can commit changes back to svn with git svn dcommit, git svn branch or git svn tag commands, but it doesn't do so unless you explicitly tell it to. svn2git only calls git svn init and git svn fetch, so it won't modify anything in the original repository.
