To migrate Auto Attendant (AA) and Subscriber Access (SA) contact objects to the new Microsoft Lync Server 2010 deployment, you first move the objects from the legacy Office Communications Server 2007 R2 deployment to the new the Lync Server deployment using the Get-CsExUmContact and Move-CsExUmContact cmdlets. On the Exchange Server, you then run the ExchUCUtil Windows PowerShell script to do the following on the newly deployed Lync pool:

Note:
In order to use the Get-CsExUmContact and Move-CsExUmContact cmdlets, you must be a member of the RTCUniversalUserAdmins group and have organizational unit (OU) permission to the OU where the contacts objects are stored. OU permission can be granted using the Grant-OUPermission cmdlet.

To move contact objects by using the Lync Server Management Shell

  1. Log on to the computer with an account that is a member of the RTCUniversalUserAdmins group or a member of the CsUserAdministrator administrative role.

  2. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell.

  3. For each pool registered with Exchange UM (where pool1.contoso.net is a pool from the Office Communications Server 2007 R2 deployment and pool2.contoso.net is the pool from the Lync Server deployment) at the command line, type the following:

    Get-CsExUmContact -Filter {RegistrarPool –eq "pool1.contoso.net"} | Move-CsExUmContact -Target pool2.contoso.net

    To verify that the contact objects are moved, run the Get-CsExumContact cmdlet and confirm that RegisrtarPool is now pointing to the new pool.

To run the ExchUCUtil Windows PowerShell script

  1. Log on to the Exchange UM Server as a user with Exchange Organization Administrator privileges.

  2. Navigate to the ExchUCUtil Windows PowerShell script.

    In Exchange 2007, ExchUCUtil.ps1 is located at: %Program Files%\Microsoft\Exchange Server\Scripts\ExchUCUtil.ps1

    In Exchange 2010, ExchUCUtil.ps1 is located at: %Program Files%\Microsoft\Exchange Server\V14\Scripts\ExchUCUtil.ps1

  3. If Exchange is deployed in a single forest, type:

    Copy Code 
    exchucutil.ps1

    Or, if Exchange is deployed in multiple forests, type:

    Copy Code 
    exchucutil.ps1 -Forest:" <forest FQDN>"

    where forest FQDN specifies the forest in which Lync Server is deployed.

    Important:
    Be sure to restart the Lync Server Front-End service (rtcsrv.exe) after you run exchucutil.ps1. Otherwise, Lync Server will not detect Unified Messaging in the topology.
