​

Skype for Business Server 2015 Enterprise Pools

The front-end servers in an Enterprise Edition pool are organized into upgrade domains (UD). These upgrade domains are subsets of front-end servers in the pool. Upgrade domains are created automatically by Topology Builder.

You must upgrade one upgrade domain at a time, and you must upgrade each front-end server in each upgrade domain. To do this, take each server in one upgrade domain offline, upgrade the server, and then continue to process the next upgrade domain. Then, repeat this process for each server in each upgrade domain. Make sure that you record the upgrade domain and servers that you have upgraded.

​

Upgrade or update Enterprise Edition pool that has two front-end servers

To do this, follow these steps:

  1. Update both of the front-end servers in the Enterprise Edition pool. To do this, follow these steps:

    1. Stop new connections to the front-end servers by running the following command on both of the front-end servers:

      Stop-CsWindowsService -ComputerName <Computer.FQDN>

    2. Run the Cumulative Server Update Installer by using the UI or by using a command to upgrade the front-end servers that are associated with an upgrade domain. 

      Notes

      • If you upgrade or update front-end servers during scheduled server downtime, you can run the Stop-CsWindowsService cmdlet in step A. This action immediately shuts down services, and the server does not wait until each existing service request is fulfilled.

      • The UI provides a clear indication of which updates are installed when you click Install Updates.

      To run the Installer, run the following command:

      SkypeServerUpdateInstaller.exe​

      • 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.

    3. The /silentmode switch applies all applicable updates in the background.

    4. Note The following text describes parameters that you can use together with the SkypeServerUpdateInstaller.exe command:

    5. Restart the server, and make sure that both front-end servers are accepting new connections.

  2. After both of the front-end servers are updated, you must run the following command: 

    Reset-CsPoolRegistrarState -ResetType FullReset

    Then, run the following command:

    Start-CsPool -PoolFqdn <Pool.FQDN>

​

Upgrade or update Enterprise Edition pool that has at least three front-end servers

To do this, follow these steps:

  1. Obtain the list of the upgrade domains for the Enterprise Edition pool that is associated with a front-end server. To do this, run the Get-CsPoolUpgradeReadinessState cmdlet on the front-end server.

  2. Update each upgrade domain.  

    Notes 

    • You must update one upgrade domain at a time.

    • All servers that are in the same upgrade domain can be updated in parallel.


    To update all servers that are in the same upgrade domain, follow these steps:

    1. Run the following command:

      Invoke-CsComputerFailover -ComputerName <Computer.FQDN>

    2. Run the Cumulative Server Update Installer by using the UI or by using a command 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:

      SkypeServerUpdateInstaller.exe

      Note The following text describes parameters that you can use together with the SkypeServerUpdateInstaller.execommand:

      • The /silentmodeswitch 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.

    3. Run the following command:

      Invoke-CsComputerFailback -ComputerName <Computer.FQDN>

    Note You must repeat step 2 to update one upgrade domain at a time until all upgrade domains in the pool are updated.
