Sometimes it is necessary to merge partial changes from one branch into another. Therefor you can use cherry-picking and merge a chosen commit into the actual branch:
$> git cherry-pick a686df3 [sprint-04 39f1473] FZMP-993- Download actual db 2 files changed, 88 insertions(+), 43 deletions(-) create mode 100644 tools/mina/config/deploy_db.rb
