Summary

This script transforms static groups into dynamic groups. The script reads a CSV file (delimited by tabs), "MyFile.csv" to identify and modify static groups into dynamic groups. The CSV file takes in DisplayName-Filter pairs.

The script will look up the groups by DisplayName, removes all its explicit members, and sets the appropriate attributes to make those groups dynamic.
