To migrate Auto Attendant (AA) and Subscriber Access (SA) contact objects to the new Lync Server 2013 deployment, you first move the objects from the legacy Office Communications Server 2007 R2 deployment to the new the Lync Server 2013 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 for the newly deployed Lync pool:

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. Open the Lync Server Management Shell.

  2. For each pool registered with Exchange UM (where is a pool from the Office Communications Server 2007 R2 deployment and is the pool from the Lync Server 2013 deployment) at the command line, type the following:

    Copy Code
    Get-CsExUmContact -Filter {RegistrarPool -eq ""} | Move-CsExUmContact -Target

    To verify that the contact objects are moved, run the Get-CsExumContact cmdlet and confirm that RegistrarPool 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

    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 2013 is deployed.

    Be sure to restart the Lync Server Front-End service (rtcsrv.exe) after you run exchucutil.ps1. Otherwise, Lync Server 2013 will not detect Unified Messaging in the topology.
