#Requires -Version 3
function Invoke-RubrikHvmFormatUpgrade
{
  <#
      .SYNOPSIS
      Connects to Rubrik and sets the forceFullSpec flag of any number of Hyper-V Virtual Machines that needs upgrade. It sets the VirtualDiskInfos to empty(default)
      so that all the disks present within the VM gets set up for a full.
 
      .DESCRIPTION
      The Invoke-RubrikHvmFormatUpgrade cmdlet will update the forceFullSpec of a given list of Hyper-V Virtual Machines.
      If these Hyper-V Virtual Machines are using the SMB backup method, their forceFull flag will be set, and they will be upgraded to use the fast VHDX method in the next backup.

      .EXAMPLE
      Invoke-RubrikHvmFormatUpgrade -VMList HypervVirtualMachine:::e0a04776-ab8e-45d4-8501-8da658221d74, HypervVirtualMachine:::9136a7ef-4ad2-4bb9-bf28-961fb74d4322
 
      This will set the forceFullspec of the given Hyper-V Virtual Machines to default, which will force a full.
 
      .EXAMPLE
      Get-RubrikVVM -hostname ad.flammi.home | Invoke-RubrikHvmFormatUpgrade
       
      This will set the forceFullSpec of the Hyper-V Virtual Machine to default belonging to the specified hostname, which will force a full
