Which tool should a Citrix Engineer use to change the priority of an application layer to meet business requirements?

App Layering stores a numeric precedence value with every application layer. Citrix documentation instructs administrators who need to raise or lower that precedence to download and run the LayerPriority utility (LayerPriority.exe / .ps1) from the Enterprise Layer Manager (ELM). The utility writes the new priority back to the App Layering database; neither the ELM console nor general-purpose PowerShell on ELM or Delivery Controllers exposes this function.

A. PowerShell on ELM server – No cmdlets exist to alter layer precedence; only the LayerPriority tool updates the database.
B. ELM Management console – UI permits editing layer properties but does not include priority/precedence changes.
C. PowerShell on Delivery Controller – Delivery Controllers have no connection to App Layering metadata; cannot modify layer order.
