PowerShell Script for SharePoint site Folder Renaming

I need a PowerShell Script that renames folders in a specific SharePoint Site (Site A) and Document Library (Library 1). The script should replace every occurrence of a dot (.) in the folder names with an underscore (_). For example, a folder named [login to view URL] should be renamed to 1234_test. The ideal freelancer for this project should have: - Extensive experience with PowerShell scripting - Proficient in SharePoint site management - Capable of implementing a CSV input feature for batch renaming - Good understanding of SharePoint's folder structure and naming conventions - Includes proper error handling and logging mechanisms. - Provides an option to undo renaming if needed. - Generates email or system alerts upon completion or error. - Supports renaming folders in multiple SharePoint sites. If the script could also accommodate a CSV file containing all the folder names that need to be renamed, that would be a plus. The script should only rename top-level folders and not include subfolders. Include detailed logs in CSV format for error handling.
