title: Porting GIT Repositories (with a lot of branches) into Gerrit
body: <p>we want to move our current GIT repositories (about 9-10) with about 20-50 branches each to gerrit. Do we really have to push each single branch (worst-case: 500 branches!) manually into gerrit or is there a better solution? The gerrit daemon will run on the current git server.</p>
