This topic explains how to install an update on an Enterprise Edition Back End Server or a Standard Edition server.

If a Back End Server is down for at least 30 minutes while you are upgrading it, users may then go into resiliency mode. When the upgrade is finished and the Back End Servers has again connected with the Front End Servers in the pool, users are returned to full functionality. If the upgrade takes less than 30 minutes, users will not be affected.

To update a back end server or Standard Edition server

  2. Download the update and extract it to the local hard disk.

  3. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Management Shell.

  4. Stop Lync Server services. At the command line, type:

    Copy Code 
    Stop-CsWindowsService

  5. Stop the World Wide Web service. At the command line, type:

    Copy Code 
    net stop w3svc

  6. Close all Lync Server Management Shell windows.

  7. Install the update.

  8. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Management Shell.

  9. Stop Lync Server services again to catch Global Assembly Cache (GAC) –d assemblies. At the command line, type:

    Copy Code 
    Stop-CsWindowsService

  10. Restart the World Wide Web service. At the command line, type:

    Copy Code

  11. Apply the changes made by LyncServerUpdateInstaller.exe to the SQL Server databases by doing one of the following:

    • If this is an Enterprise Edition Back End Server and there are no collocated databases on this server, such as Archiving or Monitoring databases, then type the following at a command line:

      Copy Code 
      Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn <SQL Server FQDN>

    • If this is an Enterprise Edition Back End Server and there are collocated databases on this server, then type the following at a command line:

      Copy Code 
      Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn <SQL Server FQDN>  -ExcludeCollocatedStores
