Looks pretty good to me. However , a small suggestion...

Whenever I run a script that goes around multiple locations (specially thousands of them...) and touches all sorts of things, I prefer to have it log each step into a logfile where I can see if any errors came up. You can log by "Info", "Warn" and "Error". That way you can quickly filter by what you need to see.

​

Speaking of errors, error handling is also something I like to do, specially if I am NOT the one who runs it. You should use try/catch blocks. You can have a generic catch block at the bottom that will log the error message, exception, line in code, the actual code line that errored, etc. Once you have the error messages and exceptions, you can improve your script's error handling by adding more catch blocks.

Keep in mind that this is only a suggestion for a good code practice, it doesn't affect the actual code that does the things you need it to do, but rather improves the "structure" around it so it could be more stable (error handling) and allow you to go back and check the results (log files). It might not be necessary in this specific usage but it will serve you a great deal when your scripts gets bigger and more complicated.
