In Sharepoint sometimes users have difficulties to grasp the permissions system.

You may have to change users membership quite a few times because ‘user X must have the same rights as User Y’.

If you have more thtan a couple of users, it can become quickly very boring.

The following snippet from the ‘lazy admin’ collection just does that: take a sharepoint group copy users to another group.

Function Copy-SPGroupToGroup {
param(
[Parameter(Mandatory=$true,Position=2)]
[string]$WebURL,
[Parameter(Mandatory=$true,Position=0)]
[string]$SourceGroupName,
[Parameter(Mandatory=$true,Position=1)]
[string]$TargetGroupName
)

$web = Get-SPWeb $WebURL

if ($web -eq $null) {
  throw "$WebURL does not match a site or site collection"
}

#Get the Source and Target Groups

$SourceGroup = $web.Sitegroups | where {$_.name -eq $SourceGroupName }
$TargetGroup = $web.Sitegroups | where {$_.name -eq $TargetGroupName }

if ($SourceGroup -eq $null) {
    throw "SourceGroup $SourceGroupName not found"
} 

if ($TargetGroup -eq $null) {
    throw "Target Group $TargetGroupName not found"
} 

#Iterate through each users in the source group

    foreach ($user in $SourceGroup.users)

    {
       $TargetGroup.AddUser($user)
        Write-Verbose "Copied $user from $SourceGroup to $TargetGroup"
        #To move users, Just remove
        #$SourceGroup.RemoveUser($user)
    }
