I’ve just recently come across an issue when performing the upgrade procedure for the Microsoft Azure Directory Sync tool with a remote SQL database. The procedure seems simple enough at first glance and is documented here.

To break down the process it is only a few simple steps:

Install the new dirsync –

Dirsync.exe /fullsql

Click next on the upgrade wizard until complete

Run Powershell –

Import-Module DirSync

Run the following PowerShell cmdlet to update the backend database –

Install-OnlineCoexistenceTool -UseSQLServer –SqlServer <ServerName> -Upgrade -Verbose -ServiceCredential (Get-Credential)

The Issue

This particular issue will occur during the upgrade procedure on the PowerShell step Install-OnlineCoexistenceTool with the following error –

VERBOSE: Running InstallOnlineCoexistenceTool in Upgrade mode.

Install-OnlineCoexistenceTool : The SQL Server Instance specified during an upgrade must match the previously

configured SQL Server Instance. Expected SQL parameter for upgrade were Server: Instance:

At line:1 char:1

+ Install-OnlineCoexistenceTool -UseSQLServer -SqlServer servername …

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : InvalidOperation: (Microsoft.Onlin…CoexistenceTool:InstallOnlineCoexistenceTool) [Inst

all-OnlineCoexistenceTool], DirectorySyncInstallException

+ FullyQualifiedErrorId : 201,Microsoft.Online.Coexistence.PS.Install.InstallOnlineCoexistenceTool

The first time I got this error, I assumed that I had provided incorrect syntax for the cmdlet and proceeded to try every variant possible. Nothing seemed to satisfy the shell so I started to look elsewhere. Next step along the process was to go look at the possible FIM configuration settings listed in the registry that I knew of –

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\FIMSynchronizationService\Parameters

I found the two keys that I ‘presumed’ that the cmdlet was using for verification –

Server = <Server FQDN>

SQLInstance = <blank>

Based on these two key values I then went back to my shell and tried to enter the syntax exactly as I could see it. I thought that maybe because my ‘SQLinstance’ value was empty, PowerShell was finding it hard for me to process this in the cmdlet of a null value. To cut a long troubleshooting story short, it didn’t matter. I had stared at the cmdlet long enough and resided to the fact that it wasn’t happy about the values stored elsewhere, and I wasn’t going to find them any time soon.

Cause

There was an issue in previous versions of DirSync where the following two registry keys were not written when installed using the /FullSQL flag –

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSOLCoExistence\storeserver

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSOLCoExistence\SQLINSTANCE

DirSync attempts to read these keys when performing the in-place upgrade to verify the SQL Server and Instance name, and then the upgrade fails when it cannot find them.

Solution

Copy value data from key –

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\FIMSynchronizationService\Parameters\Server\<ServerName>

Create a new string value of –

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSOLCoExistence\storeserver

Paste the value data from above

Copy value data from key –

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\FIMSynchronizationService\Parameters\SQLInstance

Create a new string value of –

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSOLCoExistence\SQLINSTANCE

Paste the value data from above (if any)

Note: For me this key was blank as the default instance was being used not a named instance.

Re-run cmdlet –

Install-OnlineCoexistenceTool -UseSQLServer –SqlServer <ServerName> -Upgrade -Verbose -ServiceCredential (Get-Credential)

Expected Output –

PS C:\Windows\system32> Install-OnlineCoexistenceTool -UseSQLServer -SqlServer <SQL Server NAME> -Upgrade -Verbose -ServiceCredential (Get-Credential)

cmdlet Get-Credential at command pipeline position 1

Supply values for the following parameters:

Once again we must make a big thankyou to Yaran at Microsoft PSS for helping me resolve this issue.
