$Username='[email protected]'
$Password = '************'

#region Credentials
[SecureString]$SecurePass = ConvertTo-SecureString $Password -AsPlainText -Force
[System.Management.Automation.PSCredential]$PSCredentials = New-Object System.Management.Automation.PSCredential($Username, $SecurePass)
#endregion Credentials

#connect to hubsite
Connect-PnPOnline -Url 'https://Tenant.sharepoint.com/sites/SitrName' -Credentials $PSCredentials
$OlistItems = Get-PnPListItem -List 'OldList'
foreach($item in $OlistItems) {
        #Create object
  $itemVal = @{
    'Title' = $item['Title']
  }
  Add-PnPListItem -List 'NewList' -Values $itemVal -ContentType "Item"
