How to move certain commits to be based on another branch in git?

by

The situation:

  • master is at X
  • quickfix1 is at X + 2 commits

Such that:

o-o-X (master HEAD)
     \
      q1a--q1b (quickfix1 HEAD)

Then I started working on quickfix2, but by accident took quickfix1 as the source branch to copy, not the master. Now quickfix2 is at X + 2 commits + 2 relevant commits.

o-o-X (master HEAD)
     \
      q1a--q1b (quickfix1 HEAD)
              \
               q2a--q2b (quickfix2 HEAD)

Now I want to have a branch with quickfix2, but without the 2 commits that belong to quickfix1.

      q2a'--q2b' (quickfix2 HEAD)
     /
o-o-X (master HEAD)
     \ 
      q1a--q1b (quickfix1 HEAD)

I tried to create a patch from a certain revision in quickfix2, but the patch doesn’t preserve the commit history. Is there a way to save my commit history, but have a branch without changes in quickfix1?
