Front-end servers in an Enterprise Edition pool are organized into areas of upgrade (UD). These areas of upgrade are subsets of the front-end servers in the farm created automatically during the installation.

It is necessary to update a domain at once and all of the servers front end component.

The process is now done in 4 steps:

  1. Use the Invoke-CsComputerFailOver to toggle command (stop) a front end of a domain upgrade server
     
  2. Perform the update
     
  3. Use the Invoke-CsComputerFailBack command for recovery (start) Server front end in the field of upgrading
     
  4. Perform the operation for all of the front-end of the farm servers

This article describes the installation of a cumulative update step by step on a server Skype for Business 2015 front-end on a farm in Enterprise version consisting of 3 servers.

The SkypeServerUpdateInstallerexecutable applies all updates for the role of the server in a single operation.

Step 1: A list of the fields of the farm upgrade

On the front-end server in the pool, apply the following command for a list of the areas of the farm upgrade:
 
Get-CsPoolUpgradeReadinessState
 
Skype_For_Business_Upgrade_004
 
PoolUpgradeState = Busy, verify the information put together with the command that might indicate a problem in your environment to be resolved before applying updates.

PoolUpgradeState = Ready, you can go to step 2.

It is also necessary to check the setting "isReadyForUpgrade" for each of the areas of upgrades.

 

Step: Invoke the server failover
 

Start the next command to invoke failover of server front-end constituting the area of upgrade:
 
Invoke-CsComputerFailover -ComputerName SKYPE_FE_01.nissarte.ca
 
Skype_For_Business_Upgrade_005
 
Skype_For_Business_Upgrade_006
 
Following operations carried out by the command, you can validate with Get-CsPoolUpgradeReadinessState that the server is not more active in his field of upgrade:
 
Skype_For_Business_Upgrade_007 
 
Noted that the values of the IsReadyForUpgrade setting for the other two areas for upgrades are now set to false.

Step3: Run the SkypeServerUpdateInstaller.exe application
 
Run the SkypeServerUpdateInstaller.exe executable to upgrade the field of upgrade front-end servers switched earlier.
 
It is possible to specify options at the launch of the application:
 
/silentmode: Applique toutes les mises à jours en arrière-plan;
/silentmode /forcereboot: Applique toutes les mises à jours en arrière-plan et redémarre le serveur si nécessaire;
/extractall: extrait les mises à jours dans un sous-répertoire nommé "Extracted"
 
Skype_For_Business_Upgrade_008
 

Click Install Updates. The executable will automatically deploy different upgrades.

Step:4 Invoquer le rétablissement du serveur front-end
 

Start the following command to invoke the restoration of front-end server constituting the first field of upgrade:
 
Invoke-CsComputerFailBack -ComputerName SKYPE_FE_01.nissarte.ca –Verbose
 
Skype_For_Business_Upgrade_011
 
Skype_For_Business_Upgrade_012
 

You can validate with the Get-CsPoolUpgradeReadinessState command that the server became active again in his field of upgrade:
 
Skype_For_Business_Upgrade_013
 
It is necessary then to repeat steps 1 through 3 for all the areas of upgrades.
