Merge VHDs

[DeepthaS]

Here is a slightly modified version of the script https://github.com/TheGabeMan/Hyper-V-MergeAVHDX

The problem with about script is it uses the last written time. this may be changed when we mess with an avhd file.

Modified it to use creation time instead. Thanks TheGabeMan

VHD Merge Script


# Path to AVHDX
$PathToVHDX = ""


$AlleFiles = Get-ChildItem -path $PathToVHDX  

$AlleFiles = $AlleFiles |Sort-Object -Property CreationTime

## Filter on avhdx and select the youngest
$LatestAHVDX = $AlleFiles | Where-Object { $_.Name -like "*.avhdx" } | Sort-Object CreationTime -Descending | Select-Object -First 1


While ( $LatestAHVDX.count -gt 0)
{
    ## ## Filter on avhdx and select the youngest
    Write-host "Youngest AVHDX = $($LatestAHVDX.Name) - $($LatestAHVDX.CreationTime)"

    # Merge youngest AVHDX into VDX
    $Source = $($PathToVHDX + "\" + $($LatestAHVDX.Name))
    $VHDSource = get-vhd $Source

    write-host "Merge: $source to $($VHDSource.ParentPath)"
    Merge-VHD -Path $Source -DestinationPath $VHDSource.ParentPath
