Copy folders that match names to other sub folder of matching directory

Question

I'm trying to copy folders from one directory to the sub directory of another folder if the folder names match.

The starting folder structure is like this -

Data > VR-01 

The entire VR-01 folder should be moved to the destination folder is like this -

Data > VR-0-1000 > VR-01 [match this name] > Archive > [matched folder (VR-01) should go here]

The VR's are separated out into different folders, 0-1000, 1001-2000, etc. with the same directory structure.

$startPath = "C:\Start\Data"

$destinationPath = "C:\Destination\Data"

$DestinationFolders = Get-ChildItem -Path $destinationPath -Directory | Select -ExpandProperty FullName

# for each item in the folder that is a directory (folder)

Get-ChildItem -Path $startPath -Recurse -Directory | %{

    #Get the folder name to compare it to the destination folder
    $CurrentFolderName = ($_.Name) 

    #Find matching directory for that folder

    #Where-Object 
    $DestinationFolders | ?{$CurrentFolderName -like $DestinationFolders} 

    #Copy files
    Copy-Item -Path $_.FullName -Destination $DestinationFolders -WhatIf
}

I've tried using the -match command and it failed due to the \\ character being part of the regex from what I can tell, so I switched to -like .

It looks like I'm missing a step in comparing the folder names and copying them, because from the -WhatIf command I see that it is just copying the folders over to the first subfolder without matching the name.

How I visualise your description is that in the Destination\\VR-0-1000 folder, you want to copy the source VR-01 if a VR-01 subfolder exists in VR-0-1000. There may not necesarily exist a Destination\\VR-0-1000\\VR-n .

I had a stab at it. Not guaranteed for efficiency, but I believe it will do the job.

$startPath = "C:\Start\Data"
$destinationPath = "C:\Destination\Data"

$sourceNames = (Get-ChildItem $startPath -Recurse -Directory).Name

(Get-ChildItem $destinationPath -Directory).FullName | % { 
    # For each folder named 'VR-****-****'
    Get-ChildItem -Path $_ | % { 
        # For each folder named VR-****-****\VR-****
        if($sourceNames -Contains $_.Name)
        {
            $sourceFolder = "$startPath\$($_.Name)\*"
            $destFolder = $_.FullName
            Write-Output "Copying $sourceFolder into $destFolder"
            Copy-Item -Path $sourceFolder -Destination $destFolder -Recurse
        }
    }
}

I ran it on a structure like so

C:.
├───Dest
│   ├───VR-1-2
│   │   └───VR-01
│   └───VR-3-4
│       └───VR-03
└───Start
    ├───VR-01
    ├───VR-02
    ├───VR-03
    └───VR-05

Output:

Copying C:\soverflowtest\Start\VR-01\* into C:\soverflowtest\Dest\VR-1-2\VR-01
Copying C:\soverflowtest\Start\VR-03\* into C:\soverflowtest\Dest\VR-3-4\VR-03
