Please correct me if I am posting to the wrong area, but this seems to be where most of the SMT questions are asked.

I don't fully understand something regarding the repositories. I understand that you have to mirror the repository, put it into a testing repo, then a production repo for all of your servers to be able to download the updates. What I don't understand is how to I update the production repository when a new patch it releases for the repo I have already mirrored?

From reading the manual, I understand that the testing environment is automatically updated; but how do I update the production environment with this new patch also?
