Upgrade from Azure AD Sync to Azure AD Connect

Posted by

After the release of Azure Active Directory Connect tool (http://blogs.technet.com/b/ad/archive/2015/06/24/azure-ad-connect-amp-connect-health-is-now-ga.aspx?linkId=15101770) I upgraded a customer without any big issues, but we saw some things I would like to share.

The upgrade process is very simple wizard, just click Next, Next, Finish. No issues here

But after the upgrade we had an issue with some performance counters that was not created, with this event message

Log Name: Application
Source: ADSync
Event ID: 6313
Task Category: Server
Level: Error
The server encountered an unexpected error creating performance counters for management agent “DOMAIN”.
Performance counters will not be available for this management agent.
Event Xml:
<Event xmlns=”http://schemas.microsoft.com/win/2004/08/events/event”&gt;
<Provider Name=”ADSync” />
<EventID Qualifiers=”32768″>6313</EventID>
<Security />

To resolve this issue perform these steps

Disable the synchronize task in Task Scheduler

Backup registry key: HKLM\SYSTEM\CurrentControlSet\Services\ADSync

Remove the registry key: HKLM\SYSTEM\CurrentControlSet\Services\ADSync\Performance

Create an empty registry key: HKLM\SYSTEM\CurrentControlSet\Services\ADSync\Performance

Run these commands

Net Stop ADSync

Unlodctr.exe ADSync

Lodctr.exe “C:\Program Files\Microsoft Azure AD Sync\Bin\mmsperf.ini”

Net start ADSync

Enable the synchronize task in Task Scheduler


Later we discovered that the password sync was not complete so we needed to intialize a full password sync.

And just for the record, the following command will NOT initialize a password sync

“C:\Program Files\Microsoft Azure AD Sync\Bin\DirectorySyncClientCmd.exe” initial

You need a PowerShell script that looks like this

$adConnector = “<Your source AD>” # Example “ad.contoso.com”
$aadConnector = “<Your target Azure AD>” # Example “tenent.onmicrosoft.com – AAD”

Import-Module adsync

$c = Get-ADSyncConnector -Name $adConnector
$p = New-Object Microsoft.IdentityManagement.PowerShell.ObjectModel.ConfigurationParameter “Microsoft.Synchronize.ForceFullPasswordSync”, String, ConnectorGlobal, $null, $null, $null
$p.Value = 1
$c = Add-ADSyncConnector -Connector $c

Set-ADSyncAADPasswordSyncConfiguration -SourceConnector $adConnector -TargetConnector $aadConnector -Enable $false
Set-ADSyncAADPasswordSyncConfiguration -SourceConnector $adConnector -TargetConnector $aadConnector -Enable $true

Look out in the Application log for event id like this for password sync process

650 Provision credentials batch start
656 Password Change Request
651 Provision credentials batch end
657 Password Change Result
605 Password changes failed to synchronized and have scheduled for retry
