What happens in the child branch if I delete a parent branch in git

Question

I am planning to rename a branch in my git repository. I found out that the easy way to do that is to make a new branch from that branch and give it the desired name.

Answer 1

Simply use git format-patch origin -o {output_folder}.

After getting all the patches out, go to the master and create a new branch.

Then apply those patches as so: git am {output_folder}/{patch_name}.patch.

Then after verifying you didn't loose any info, you can delete the old branch with git Branch -D {name_old_branch}
