Migrate Git Repo's Remote Origin And Set Tracking Branches

new_origin.sh

NEW_REMOTE="[email protected]:your/repo.git"

# Rename the old origin
# Add the new origin
# Push all local branches to new origin and set respective tracking branches
git remote rename origin old_origin
git remote add origin $NEW_REMOTE
git remote push --all -u origin

# NOTE: Could benefit from refactor to use a "git clone --mirror" flow
#       which would push *all* branches on old_origin to the new origin,
#       not just those locally checked-out.
