Batch migrations from On-Premises SharePoint data to SharePoint Online, can be made more efficient with Sharegate PowerShell and SharePoint Online PnP PowerShell Cmdlets.

In most case, you would want to migrate only custom lists and libraries that are actively used and preserve items permissions, by merging the SharePoint defaults Owners, Members and Visitors groups.

This script migrate an array of lists and libraries that could be generated with the Sharegate Reporting by filtering only certain lists and libraries conditions:

Prior to run the script, you will need to install SharePoint Online PnP PowerShell module:

Install-Module SharePointPnPPowerShellOnline

then generate the password secure strings for your environment:

($Credential=Get-Credential).Password | ConvertFrom-SecureString

an finally populate array of List and Libraries:

$ListsToTransform = @(
"Documents",
"Quick links",
"Team Documents",
"Public Pictures"
)
