Usually, after deployment to the production environment a new tag is created in git marking successful production deployment, so later when working on defects it would be much easy to investigate any issues, having the same code as deployed to production. The best way to work with git tags is to create a new branch from the existing tag. It can be done using git checkout command.
git checkout -b new-branch-name tag-name
