You can use git cherrypick to pick a commit from one branch to another. Sometimes it is usefull to bring a range of commits. So you can:

git cherry-pick <oldest-commit-sha>..<newest-commit-sha>

However, the way cherrypick works is a bit non-intuitive. The code above does not include the oldest sha, but it includes the newest sha (and everything in between).

In order to include the oldest sha, then you can make use of ^:

git cherry-pick <oldest-commit-sha>^..<newest-commit-sha>

The code above includes the oldest sha, the newest sha and everything in between.
