Migrate OneDrive for Business to OneDrive for Business with PowerShell
Updated this week

Use PowerShell to automate your OneDrive for Business to OneDrive for Business migration.

Index

Prerequisites

Note: You must be site collection admin on each OneDrive, even if you have higher admin privileges. In step (9) below, you will use SharePoint admin or global admin permissions to apply site collection permissions to all your OneDrives. The PowerShell script will remove the site collection admin permissions as you migrate each OneDrive.

How-to

Tip: To migrate your documents to a new folder in your OneDrives, see Walkthrough - Migrate to a new OneDrive folder in PowerShell.

Create a CSV guide for your migration

  1. Go to All reports.

  2. Click Create custom report in the top right corner.

  3. Select OneDrive for Business as your object type.

  4. Click Continue without saving.

  5. Select your source Tenant.

  6. Click Run.

  7. Select all your OneDrives with the checkmark box at the top of the list.

  8. Click Edit in the Quick actions menu

  9. Select Add administrators in the Transformations dropdown.

  10. Search and add your account in the Select user or group field that appears.

  11. Click Apply.

  12. Click Back two times to go back to your report results.

  13. Click Export in the top right corner.

  14. Save the file on your drive.

  15. Repeat steps (1) to (14), selecting your destination tenant at step (5).

  16. Open Excel.

  17. Add titles SourceSite and DestinationSite to the first two columns.

  18. Open the two files you saved in steps (14) and (15).

  19. Combine the data from both files into the new document so that the source URL corresponds to the destination URL under their respective column.

    If sorting alphabetically doesn't work, you can reorganize your data manually or use Excel macros or PowerShell to find a solution.

  20. Save this new file as a CSV on your drive.

Create your script

Copy and paste the following script into the PowerShell application of your choice.

Import-Module Sharegate
$csvFile = "C:\CSV\CopyContent.csv"
$table = Import-Csv $csvFile -Delimiter ","$srcUsername = "sourceusername"$srcPassword = ConvertTo-SecureString 'sourcepassword' -AsPlainText -Force$dstUsername = "destinationusername"$dstPassword = ConvertTo-SecureString 'destinationpassword' -AsPlainText -ForceSet-Variable srcSite, dstSite, srcList, dstList
foreach ($row in $table) {    Clear-Variable srcSite    Clear-Variable dstSite    Clear-Variable srcList    Clear-Variable dstList    $srcSite = Connect-Site -Url $row.SourceSite -Username $srcUsername -Password $srcPassword    $dstSite = Connect-Site -Url $row.DestinationSite -Username $dstUsername -Password $dstPassword    $srcList = Get-List -Site $srcSite -Name "Documents"
    $dstList = Get-List -Site $dstSite -Name "Documents"
    Copy-Content -SourceList $srcList -DestinationList $dstList    Remove-SiteCollectionAdministrator -Site $srcSite    Remove-SiteCollectionAdministrator -Site $dstSite}

Adjust your script so that it will work for you. Here are a few guidelines:

  • $csvFile: Adjust the path to point to the CSV file you saved before.

  • $table: The delimiter is the symbol your CSV uses to separate items in a row. Ensure your script uses the same delimiter as your file (a quick way to verify this is by opening the CSV with Notepad).

  • $srcUsername, $srcPassword, $dstUsername, and $dstPassword: Replace "sourceusername", 'sourcepassword, "destinationusername", and 'destinationpassword' with your Microsoft 365 credentials.

  • Connect-site: The command to connect to a SharePoint site. If you need to change the authentication method, see Connect Site.

  • Set-variable and Clear-Variable: These commands help prevent an issue where a connection failure can cause your data to end up in the wrong OneDrive.

  • foreach: We use foreach to loop through the values in your CSV file. You can find more about it here.

  • Remove-SiteCollectionAdministrator: This function removes your user account as site collection administrator on OneDrive after its migration. For more information, see Remove Site Collection Administrator.

Run your script once it's properly adjusted and tested.
