Convert Classic Pages from Publishing Site - Unable to connect to SharePoint On-Premise environment using 'Connect-PnPOnline'

[gopaltiwari]

Hi,

I am trying to convert On-Premise (SharePoint 2013) Classic Publishing pages to SharePoint online (Modern) pages. I am trying to follow the example given in below article:
Transform Classic Publishing Pages to Modern Pages using PnP

I am getting stuck at the very first step itself when I am trying to get a connection object from SharePoint 2013 on-prem environment:

$sp13Conn = Connect-PnPOnline "" -Credentials OnPrem -ReturnConnection -TransformationOnPrem

Here is another article which describes the same method:
Convert Classic Publishing Pages to Modern Pages

Due to recent Changes in PnP Management Shell registration, 'Connect-PnPOnline' no longer works with -Credentials OR -Interactive with -TransformationOnPrem parameters.

I also registered an Entra ID App to use with PnP by following below articles:
https://pnp.github.io/powershell/articles/registerapplication.html

Still, I am unable to connect to SharePoint 2013 On-Prem environmet using 'Connect-PnPOnline'.

Environment Details:
I am using latest PnP.PowerShell to execute PowerShell script.
PowerShell version 7.2 (Visual Studio Code)

Please let me know if 'Connect-PnPOnline' command can still be used to connect to SharePoint On-Prem environment.
if yes, please share a sample code.
