Copy members from one AD Group to another, get members from an AD group

Powershell is powerful and versatile to perform numerous operations. It has been recently useful for me when i needed to migrate users from one AD group to another. Below is a one line statement to do just that

Add-ADGroupMember -Identity 'New Group' -Members (Get-ADGroupMember -Identity 'Old Group' -Recursive)

The -Recursive switch is used in case the old group contains nested groups.

What if you need to get all the users contained in an AD group?

There is a one line powershell statement for that too.

Get-ADGroupMember -Identity 'SQLADGroup' -Recursive | select name | Sort-Object -Property name

Sort-Object will take the previous output and sorts the name column in ascending order.
