Some things consider before doing this… Please use my own personal experience of why you shouldn’t do this.
The original person that had created a rogue PS script had left the company as well as the original team.
So when I came on board I identified a 3 year old file that had not been touched since creation on the server.
The original team that knew about it was also gone and it was decided to remove it because “nothing” was using it.
Until we did it in prod and certain processes started breaking that the team was not aware of nor, I.
Specifically the code block where you pass in a file path and then execute a rogue PS script.
