I have a "master" branch and a "master new" branch.
The "master new" is a result of a mistake that was needed to be fixed quickly.
I know it is a very bad practice to do that but thats were I am now.
For a while now I have been working as if as the "master new" is my master branch, opening branches from it etc.
My question is if there is a safe and easy way to make the "master" branch identical to the "master new" branch so I can start working with it and stop working from the "master new" branch?
