SharePoint 2010 Claims to Classic PowerShell help

Question

I have a client requirement to move from Classic to Claims. I'm currently utilizing some PowerShell from http://derekmartin.org/archives/701

$webApp =
$farm = get-SPFarm
$wa = get-SPWebApplication $webApp
$site = get-SPSite $webApp
$web = $site.OpenWeb()
foreach ($user in $web.AllUsers) {
   $newuser = $user
   $newuserLoginName = “”
   write-host($user.LoginName)
   if ($newuser.LoginName.StartsWith(“i:0#.w|”))
   {
      ! $newuserLoginName = $user.LoginName.Substring(7)
   }
   $user = $newuser
   $farm.MigrateUserAccount($user.LoginName, $newuserLoginName, $false)
}

Unfortunately every time I try to run it I get the following

Invalid assignment expression. The left hand side of an assignment operator needs to be something that can be assigned to like a variable or a property. At C:\Users\user\Desktop\claims.ps1:12 char:22 + ! $newuserLoginName = <<<< $user.LoginName.Substring(7) + CategoryInfo : ParserError: (:) [], ParseException + FullyQualifiedErrorId : InvalidLeftHandSide

Any idea on what could be wrong?

Thanks!

Sorry forgot to paste the script in question in originally!

Answer 1

I may be wrong but I suppose that the exclamation mark on the

!$newuserLoginName = $user.LoginName.Substring(7)

line should just be a refuse (or at last it doesn't match any syntax I am aware of).

If you are on a test environment or are otherwise sure that you won't damage your system with a wrong comand, I would try to replace the if with:

if ($newuser.LoginName.StartsWith(“i:0#.w|”))
{
   $newuserLoginName = $user.LoginName.Substring(7)
}

The if should simply remove the "claim specific part" from the login name, so I would assume the original blog post intended it this way.

That said, know that I have never done this before and are only trying to spot an error in the powershell code. I don't know if that code will actually do what promised, so use that at your risk (or wait some more expert other user to confirm the behaviour).
