Changing RunAs account in SCOM 2012R2

Question

For SCOM 2007R2, we had SetActionAccount.ps1 to change the RunAs account for a group of servers (from the console, via OM shell). Does anyone have a way to change the RunAs account for a group of servers in 2012R2? I'm not smart enough to hack the SetActionAccount.ps1
for 2012R2.

Hi,
param ([string]$newActionAccountName)
$str=get-history | select-object -first 1
$str=$str.commandline | out-string
$start = $str.indexOf("-Id") + 4
$end = $str.indexOf(" ;", $start)
$length = $end - $start
$context = $str.substring($start, $length)
$Group = Get-SCOMGroup -id $context
$mg = Get-SCOMManagementGroup
$newActionAccount = Get-SCOMrunAsAccount -Name $newActionAccountName
$actionAccountRunAsProfile = $mg.GetMonitoringSecureReferenceForActionAccount()
if ($newActionAccount -eq $null -or $newActionAccount.Count -eq 0)
throw "Action Account '$newActionAccountName' was not found."
if ($newActionAccount.Count -gt 1)
throw "More than one action account was found with the same names as '$newActionAccountName'."
$ComputerGroup=$Group.GetRelatedMonitoringObjects().DisplayName
$healthServices=Get-SCOMClassInstance -Class (Get-SCOMClass -Name "Microsoft.SystemCenter.HealthService") | ? {$ComputerGroup -eq $_.displayname}
$secureDataHSRefs = $mg.GetMonitoringSecureDataHealthServiceReferenceBySecureReferenceId($actionAccountRunAsProfile.Id) |
where {$healthServices -contains $mg.GetPartialMonitoringObject($_.healthServiceId)}
foreach($secureDataHSRef in $secureDataHSRefs)
$healthService = $mg.GetMonitoringObject($secureDataHSRef.HealthServiceId)
$currentActionAccount = $mg.GetMonitoringSecureData($secureDataHSRef.MonitoringSecureDataId)
"Computer: '" + $healthService.DisplayName + "' ...changing action account" + "'`n From: '" + $currentActionAccount.Name + "'`n To : '" +
$newActionAccountName + "'"
$secureDataHSRef.MonitoringSecureDataId = $newActionAccount.Id
$secureDataHSRef.Update()
