Split git branch into separate repo

According to project setup I would rather

1) create new repo for v1

git checkout v1
git remote add v1_repo [email protected]:andrej/project-v1.git
git push v1_repo v1:master

2a) merge v2 into master branch.

git checkout master
git merge v2

2b) if you insist on making 2 new projects then you can create new project from the newly merged master:

git remote add v2_repo [email protected]:andrej/project-v2.git
git push v2_repo master

3) You can tidy up original repo by deleting v1 and v2 branches:

git checkout master
git branch -D v1
git branch -d v2

You have to use -D for force delete branch v1 here because v1 branch it was not merged.

The following assumes you have your two separate new repos set up as remotes named repo_v1 and repo_v2.

The v1 branch is easy:

git push repo_v1 ref_c:v1

The v2 branch isn't that hard:

git checkout --orphan v2 ref_b
git cherry-pick ref_b..ref_d
git push repo_v2 v2

(git checkout --orphan <branchname> <startpoint> creates an entirely new history that starts from the specified point but doesn't have any of that commit's parents.)
