Step 1: Install the cumulative updates

Lync Server 2013 Enterprise Pools

Upgrade or Update Front End servers

1. On a front-end server in a pool, run the following cmdlet:
   
   Get-CsPoolUpgradeReadinessState
   
   If the State value of the pool is Busy, wait for 10 minutes, and then try to run the Get-CsPoolUpgradeReadinessState cmdlet again. If you see Busy at least three consecutive times after you wait 10 minutes in between attempts, or if you see a result of InsufficientActiveFrontEnds for the State value of the pool, there is an issue that is affecting the pool. If you cannot resolve this issue, you may have to contact Microsoft Support. If this pool is paired with another front-end pool in a failure recovery topology, you must fail the pool over to the backup pool, and then update these servers in this pool. For more information about how to fail over a pool, go to the following Microsoft website:
   
   
   Failing over a pool in Lync Server 2013
   If the State value of the pool is Ready, go to step 2.
2. The Get-CsPoolUpgradeReadinessState cmdlet also returns information about the upgrade domains in the pool, and about which front-end servers are in each upgrade domain. If the ReadyforUpgrade value for the upgrade domain that contains the server that you want to upgrade is True, you can upgrade the server. To do this, follow these steps:
3. 
   
   
   1. Stop new connections to the front-end servers by using the Stop-CsWindowsServices -Graceful cmdlet.
   2. Run the Cumulative Server Update Installer by using the UI or a command to upgrade the front-end servers that are associated with an upgrade domain.
      
      Note If you upgrade or update front-end servers during scheduled server downtime, you can run the cmdlet in step 2 without the -Graceful parameter. More specifically, run the cmdlet as Stop-CsWindowsService. This action immediately shuts down services, and the server does not wait until each existing service request is fulfilled.
      
      Note The UI provides a clear indication of which updates are installed when you click Install Updates.
      
      To run the Installer, run the following command:
      
      

      LyncServerUpdateInstaller.exe 

      
      Notes
      The following text describes parameters that you can use together with the LyncServerUpdateInstaller.exe command:
      
      
      • The /silentmode switch applies all applicable updates in the background.
      • The /silentmode /forcereboot switches together apply all applicable updates in the background, and then automatically restart the server at the end of the installation process, if it is necessary.
      • The /extractall switch extracts the updates from the installer, and then it saves the updates in a subfolder that is named Extracted in the folder from which you ran the command.
   3. Restart the server and make sure that it is accepting new connections.

Lync Server 2013 Standard Edition and other roles

1. Run the Cumulative Server Update Installer by using the UI, or by running a command line to upgrade the front-end servers that are associated with an upgrade domain.
   
   Note The UI provides a clear indication of which updates are installed when you click Install Updates.
   
   To run the Installer, run the following command:
   
   

   LyncServerUpdateInstaller.exe 

   
   Notes The following text describes parameters that you can use together with the LyncServerUpdateInstaller.exe command:
   
   
   • The /silentmode switch applies all applicable updates in the background.
   • The /silentmode /forcereboot switch applies all applicable updates in the background, and then automatically restarts the server at the end of the installation process if this is necessary.
   • The /extractall switch extracts the updates from the installer and saves the updates in a subfolder that is named "Extracted" in the folder in which you ran the command.
2. Restart the server if it is required by the installation wizard.

Step 2: Apply the back-end database updates

Lync Server 2013 Standard Edition

Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn
<SE.FQDN>
-Verbose 

• In this command, <SE.FQDN> is a placeholder for the appropriate value.
• You must run this cmdlet on the Lync Server 2013 Standard Edition server.

Lync Server 2013 Enterprise Edition

Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn <FEBE.FQDN> -Verbose 

Lync Server 2013 Persistent Chat Databases

Install-CsDatabase -DatabaseType PersistentChat -SqlServerFqdn <PChatBE.FQDN> -SqlInstanceName <DBInstance> -Verbose 

Lync Server 2013 Monitoring/Archiving/Persistent Chat Databases

Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn <SQLServer.FQDN> -Verbose 

Step 3: Apply the Central Management Database update

• If the Central Management Store is hosted on a Lync Server 2010 Standard Edition Server or Enterprise pool, do not run the Install-CsDatabase -CentralManagementDatabase command.
• If the Central Management Store is hosted on a Lync Server 2013 Standard Edition Server or Enterprise pool that was previously updated with the Lync Server 2013 February 2013 cumulative updates, do not run the Install-CsDatabase -CentralManagementDatabase command.

Install-CsDatabase -CentralManagementDatabase -SqlServerFqdn <CMS.FQDN> -SqlInstanceName <DBInstanceName> -Verbose 

• In this command, <CMS.FQDN> and <DBInstanceName> are placeholders for the appropriate values.
• In a coexistence environment that contains both Lync Server 2010 and Lync Server 2013 and in which the Central Management Service is located on a Lync Server 2010 pool, do not run the Install-CsDatabase -CentralManagementDatabase command. If you later move the Central Management Service to a Lync Server 2013 pool, you have to run the Install-CsDatabase -CentralManagementDatabase command to apply the changes.

Step 4: Enable the Mobility service

Step 5: Enable the Unified Communications Web API
