How can I achieve this outcome with GIT?
Thank you.
I tried branching off of the original branch and merging it with my local branch. I tried pulling the remote branch into my local branch. I'm trying to avoid reconstructing all of my work manually on a fresh branch off the old directory.
In your new branch, add and commit if you haven't already.
Switch to the other branch, the old one that still contains the old directory with the old name.
git switch oldbranch
Now you can see the old directory with the old name, right there in your working tree. Move the directory to a new location outside your working tree.
Now
git reset --hard
git switch -
Now you're back where you were, in the new branch with the new version of the directory. Move the old directory back into your working tree. Done. You now have both.
