How to Use Powershell to Turn Static Groups into Dynamic Groups
FIM ScriptBox Item
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.
