  • I got the same error too. Any one know how to handle that??

  • I got the following error: The term ‘Get-SPWeb’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

    • This script is written for SharePoint On-premises and must be executed from any of the SharePoint server in the farm.

  • Hi,

    Is there any script available for SharePoint Online to perform this activity.

  • Hi Does this also copy the SharePoint Groups from the source or it just copies users and their permissions?

    E.g Managers …. Full Control or Name.Surname … Full Control?

    • This script copies all users and groups – that has permissions to source web to the target!
