Git: Put last 3 commits into branch, reset master

Question

I'm trying to perform some git surgery here. My series of commits currently looks like this:

A->B->C->D->E->F

and I want to transform it so that it looks like this (last commit in master is C ):

A->B->C

and

D->E->F live in a branch off of commit C

How might I do this?

Answer 1

Simply create a new branch from your current master:

git checkout master
git checkout -b newBranch
git push -u origin newBranch

A-B-C-D-E-F (master, NewBranch)

Then reset master (making sure you don't have any work in progress)

git checkout master
git reset --hard C

A-B-C (master)
     \
      D-E-F (newBranch)

You will need to git push --force origin master , so make sure you are the only one working on it.
