Uninstallation methods

Uninstall the cumulative updates

Remove cumulative updates from an Enterprise Edition pool that has two front-end servers

To do this, follow these steps:

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

    Stop-CsWindowsService -ComputerName <Computer.FQDN>

  2. Uninstall any cumulative updates.

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

  4. After both 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>

Remove cumulative updates from an 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. Uninstall any cumulative updates for each upgrade domain.

    Notes

    • You must uninstall cumulative updates from one upgrade domain at a time.

    • You can remove cumulative updates in parallel from all servers that are in the same upgrade domain.


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

    1. Run the following command:

      Invoke-CsComputerFailover -ComputerName <Computer.FQDN>

    2. Uninstall cumulative updates on front-end servers that are associated with an upgrade domain.

    3. Run the following command:

      Invoke-CsComputerFailback -ComputerName <Computer.FQDN>

    Note You must repeat step 2 to uninstall cumulative updates from every upgrade domain until all upgrade domains in the pool are updated.

You must perform several configuration operations, depending on the kind of Skype for Business 2015 Enterprise Edition back-end servers that you are using.

Note If database mirroring is enabled for the back-end databases, we strongly recommend that you use the Invoke-CsDatabaseFailover -NewPrincipal Primary command, and then run the Get-CsDatabaseMirrorState -PoolFqdn <fqdn of pool> cmdlet to verify that the primary server is principal for all databases before you run the Install-CsDatabase cmdlet. If Persistent Chat is collocated (the Persistent Chat front-end service and back-end database are running on the same server), you must run the Install-CsDatabase cmdlet together with the ExcludeCollocatedStores parameter.

Skype for Business Server 2015 Monitoring Databases

If Skype for Business Monitoring databases are deployed on stand-alone SQL databases, run the following command:

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

In this command, <FEBE.FQDN> is a placeholder for the actual value.

Skype for Business Server 2015 Standard Edition and other roles

  1. Uninstall cumulative updates on the Standard Edition or any other server role.

  2. Restart the server if it is required to do this after you uninstall these updates.
