To begin the migration, we have to clone the Subversion repository locally, as we did earlier; I again recommend adding the --stdlayout option, to preserve branches and tags, and then to adding the -A option to let Git convert commit authors while cloning:

$ git svn clone <repo-url> --stdlayout --prefix svn/ -A authors.txt 

In case the Subversion repository has trunk, branches, and tags located in other paths (so not a standard layout), Git provides you with a way to specify them with the --trunk, --branches and --tags options:

$ git svn clone <repo-url> --trunk=<trunk-folder> --branches=<branches-folder> --tags=<tags-folder>

When you fire the clone command, remember that this operation can be time consuming; in a repository with a thousand commits, it is not unusual to wait for one or two quarters of an hour.
