Citrix Virtual Apps and Desktops SDK


Moves all MachineCreation Service tasks from the current execution host to another.


Switch-ProvTask [-Host2] <String> [-LoggingId <Guid>] [-BearerToken <String>] [-TraceParent <String>] [-TraceState <String>] [-VirtualSiteId <String>] [-AdminAddress <String>] [<CommonParameters>]

Detailed Description

Enables tasks running within the MachineCreation Service to be moved from one execution host to a different host.

Tasks can only execute on a single host. If the host is removed from a deployment, the tasks cannot continue to execute. These ‘orphaned’ tasks can be moved to a different host within the deployment so that they can continue to execute. All tasks must be moved; there is no mechanism to move individual tasks. Run the Switch-ProvTask command against the host to which the tasks are to be moved; that is, if you are not running the command directly on the host, use the AdminAddress parameter to specify the host to which tasks will be moved.


Name Description Required? Pipeline Input Default Value
Host2 Specifies the host from which the tasks should be removed. true false  
LoggingId Specifies the identifier of the high-level operation this cmdlet call forms a part of. Citrix Studio and Director typically create high-level operations. PowerShell scripts can also wrap a series of cmdlet calls in a high-level operation by way of the Start-LogHighLevelOperation and Stop-LogHighLevelOperation cmdlets. false false  
BearerToken Specifies the bearer token assigned to the calling user false false  
TraceParent Specifies the trace parent assigned for internal diagnostic tracing use false false  
TraceState Specifies the trace state assigned for internal diagnostic tracing user false false  
VirtualSiteId Specifies the virtual site the PowerShell snap-in will connect to. false false  
AdminAddress Specifies the address of a XenDesktop controller the PowerShell snap-in will connect to. You can provide this as a host name or an IP address. false false Localhost. Once a value is provided by any cmdlet, this value becomes the default.
