After migrating our SharePoint environment, we identified duplicated files between the original and migrated sites.
we need to perform a comprehensive comparison of files between the source (original SharePoint) and target (migrated SharePoint) environments.

    To perform a comprehensive comparison of files between your original SharePoint site and the migrated SharePoint site, you'll want to identify duplicates, missing files, and any discrepancies in metadata (like modified dates, file sizes, or authors).

    Here's a step-by-step approach:

    Step 1: Export File Metadata from Both Sites

    Use PowerShell with the PnP PowerShell module to extract file metadata from both environments.

    Example command:

     

    # Connect to SharePoint

    Connect-PnPOnline -Url "https://yourtenant.sharepoint.com/sites/YourSite" -Interactive

    # Export file metadata

    Get-PnPListItem -List "Documents" -PageSize 500 | 

    Select-Object -Property FileLeafRef, FileRef, Author, Editor, TimeCreated, TimeLastModified |

    Export-Csv -Path "OriginalSiteFiles.csv" -NoTypeInformation

    Step 2: Compare the Two CSV Files

    Once you have both CSVs, you can compare them using Excel, Power BI, or a script (Python or PowerShell).

    Would you like me to help you:

    • 📥 Create a Python script to compare the two CSVs?
    • 🧾 Generate a report showing duplicates, missing files, and mismatches?

    If you already have the CSVs, feel free to upload them here, and I can help you analyze them directly.
