One Drive Migration

Question

I'm trying to migrate a file server to One Drive the problem is that there are many folders and files with special characters like '|' , '<' etc..

And also for some reason that company used '*' for versioning like :

'*' => v.1
'**' => v.2

etc...

So I wrote a Powershell script that renames all the files and folders that include a special characters.

#Files
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace(":","-")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("<","-")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace(">","-")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("?","-")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("/","-")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("|","-")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("**********","10")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*********","9")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("********","8")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*******","7")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("******","6")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*****","5")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("****","4")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("***","3")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("**","2")}
Get-ChildItem -File -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*","1")}


#Directories
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace(":","-")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("<","-")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace(">","-")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("?","-")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("/","-")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("|","-")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("**********","10")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*********","9")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("********","8")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*******","7")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("******","6")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*****","5")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("****","4")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("***","3")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("**","2")}
Get-ChildItem -Directory -Recurse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*","1")}

So this works fine but for some reason I'm getting many error when renaming the folders even though it worked...

Error:

 … curse | % { Rename-Item -Path $_.PSPath -NewName $_.Name.replace("*", …
     |                ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Source and destination path must be different.

I also tried what this thread suggest but this didn't work for me:

Does anyone have a clue why I'm getting this error? And How to fix it?

Thanks in advance.

The error is normal, if you dont have reasons to rename the directory or file because the filename is ok and no character to modify, the name stays same, so an error is displayed saying you cant rename a file/directory with same name.

Despite this error, the process is not stopped and has no impact on the final result

i suggest you to set all couple key to search , new value in an object:

#add your template to replace
$r = @{
    ":" = "-"
    "<" = "-"
    "**********" = "10";
    "*********" = "9";
    "********" = "8"
    }

$Folders=Get-ChildItem -Directory -path -Recurse

foreach($folder in $Folders){
    $newname = $folder.Name

    foreach($k in $r.Keys){
         $newname = $newname.Replace($k,$r.$k) 
    }

    #rename only if original name and newname are differents
    if(!$newname.equals($folder.Name)){
        Rename-Item -Path $folder.FullName -NewName $newname
    }
}

do samething for your files......
