Merge-AVHDXwithnoCheckpoints: Unterschied zwischen den Versionen

   <#
   .Synopsis
      Merge all AVHDX of a VM with the ParentDisk (.vhdx)
   .DESCRIPTION
      IMPORTANT: Use this script only if you have AVHDX-Files but no Checkpoints on the Hyper-V Node -> Get-VM | Get-VMCheckpoint
   .EXAMPLE
      Merge-AVHDXwithnoCheckpoint -VMName <VMName> -VMMServer <VMMServer>
      and configure the original .VHDX in Failover Cluster Manager (Select the ParentDisk (.vhdx) for each Disk)
