How to move a folder from one repo to another and keep its commit history
# source: http://st-on-it.blogspot.com/2010/01/how-to-move-folders-between-git.html
# First of all you need to have a clean clone of the source repository so we didn't screw the things up.
git clone git://server.com/my-repo1.git
# After that you need to do some preparations on the source repository, nuking all the entries except the folder you need to move. Use the following command
git filter-branch --subdirectory-filter your_dir -- -- all
# This will nuke all the other entries and their history, creating a clean git repository that contains only data and history from the directory you need. If you need to move several folders, you have to collect them in a single directory using the git mv command.
