Exchange UM Association Migration from Lync 2010 to Lync 2013

Primarily this tasks involve following steps...

1.1  Move Exchange UM Contact objects

Currently Exchange UM contact objects are homed at Lync 2010 pool. We need to move them to 2013 pool using following command.

 Get-CsExUmContact -Filter {RegistrarPool -eq "Lync 2010 Pool FQDN"} | Move-CsExUmContact -Target Lync 2013 Pool FQDN

1.2  Run the ExchUCUtil Windows PowerShell script

  • Log on to the Exchange UM Server as a user with Exchange Organization Administrator privileges.
  • Navigate to the ExchUCUtil Windows PowerShell script (%Program Files%\Microsoft\Exchange Server\V14\Scripts\ExchUCUtil.ps1).
  • Type exchucutil.ps
  • 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.
1.3  Add Lync 2013 UM IP Gateway

Add and associate Lync 2013 UM IP Gateway with Exchange UM objects. http://technet.microsoft.com/en-us/library/aa998045(v=exchg.150).aspx

1.4  Disable Lync 2010 UM IP Gateway

We can disable the Lync 2010 UM IP Gateway and check the UM functionality before deleting it.

Use the EMC in Exchange 2010 to disable a UM IP gateway

  • In the console tree, navigate to Organization Configuration > Unified Messaging.
  • In the result pane, click the UM IP Gateways tab.
  • In the work pane, select a UM IP gateway that you want to disable.
  • In the action pane, click Disable immediately.
  • In the confirmation dialog box, click Yes to confirm.

1.5 Delete Lync 2010 UM IP Gateway

I usually don't recommend deleting Lync 2010 UM IP Gateway immediately after disabling the gateway. Ideally we should test the UM functionalities thoroughly before deleting 2010 gateway. After testing the setup with Lync 2010 UM IP Gateway disabled, we can follow the steps below to delete the Lync 2010 UM IP Gateway.

Use the EMC in Exchange 2010 to delete a UM IP gateway:

  • In the console tree, navigate to Organization Configuration > Unified Messaging.
  • In the result pane, click the UM IP Gateways tab.
  • In the work pane, click the UM IP gateway that you want to delete.
  • In the action pane, click Remove.
  • In the confirmation dialog box, click Yes.

  1. What are the steps to enable Exchange UM for Lync 2013 running side by side with Lync 2012( UM enabled for Lync 2010 already)? Thank you?
