Can I reinstall Homebrew while keeping all my packages?

I had reinstalled Homebrew because I had trouble installing packages from taps. If I ever have to do so again I'd like to without removing my packages. Running the Homebrew uninstall script NONINTERACTIVE=1 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)" and then installing it again : /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" deletes all my packages.
