This script can be used to update group membership based on source user’s group membership. The input for this script the user name (sAMAccountName) and it assumes that the source and target sAMAccountName are the same. Input file (Users.csv) Format: Script validates users in the source domain and collect “memberof” details and then add the target user (migrated user) to the same group. At the end of the operation, the source user and the target user (migrated user) will be part of same security group in the source domain. You can see some other “Update Group Membership” script here - http://portal.sivarajan.com/2014/01/update-group-membershippowershell-script.html Script: # # Update Group Membership # Santhosh Sivarajan (Santhosh@Sivarajan.Com) # Clear Import-Module ActiveDirectory $userN = "" $GroupDetails = "" $Group = "" $GroupsDN = "" $uValidation = "" $tagetDomain = "labanddemo.com" $Cdate = (Get-Date).tostring("dd-MM-yyyy-hh-mm-ss") $SGBeforeUpdateFile = New-Item -type file -force "C:\Temp\Groups_Before_$Cdate.csv" $SGAfterUpdateFile = New-Item -type file -force "C:\Temp\Groups_After_$Cdate.csv" Import-CSV "C:\Temp\Users.csv" | % { $userN = $_.userName $sourceDomain = $_.Domain $uValidation = Get-ADUser -filter {sAMAccountName -eq $userN} -Server $tagetDomain If($uValidation -eq $Null) { Write-Host "User $userN Doesn't Exist in $tagetDomain Domain" $errorFile = New-Item -type file -force "C:\Temp\Error_$Cdate.csv" "User $userN Doesn't Exist in $tagetDomain Domain"| Out-File $errorFile -encoding ASCII -append } Else { $userN | Out-File $SGBeforeUpdateFile -encoding ASCII -append $GroupDetails = get-aduser -Server $sourceDomain -identity $userN -Properties memberof $GroupsDN = $GroupDetails.memberof $GroupsDN | Out-File $SGBeforeUpdateFile -encoding ASCII -append foreach ($Group in $GroupsDN) { $MigrateduserN = Get-ADUser $userN -Server $tagetDomain -Properties DistinguishedName Write-host "Adding User -> $MigrateduserN" Write-host "To Group -> $Group" Add-ADGroupmember -Server $sourceDomain -Identity $Group -Members $MigrateduserN $members = Get-ADGroupmember -Server $sourceDomain -Identity $Group $GroupName = Get-ADGroup -Server $sourceDomain $Group $GroupName.Name | Out-File $SGAfterUpdateFile -encoding ASCII -append $members.distinguishedName | Out-File $SGAfterUpdateFile -encoding ASCII -append Write-host "....Done!" -ForegroundColor Green Write-host "" } } } Download: You can also download the script from the following locations: OneDrive TechNet Gallery Read More Reactions: Friday, March 23, 2018 Group Membership Report – PowerShell Script Friday, March 23, 2018 2:00 AM Unknown 22 comments Another “Group Membership Report” script.
