Hello Experts,

I am trying to upgrade from BC23 (23.9.21328.0) to BC24(24.4.22295.22925).

however when i do a navdataupgrade for System application I get below error:
'System Application' by 'Microsoft' from version '23.9.21328.0' to '24.4.22295.22925' for tenant 'default' and company 'BAKC' due to the
following error: 'An item with the same key has already been added. Key: 00000000-0000-0000-0000-000000000000'.
 

I have followed all the process , but got stuck here:
Start-NAVAppDataUpgrade -ServerInstance BC240 -Name "System Application" -Version 24.4.22295.22925 -SkipVersionCheck
Install-NAVApp -ServerInstance BC240 -Name "Business Foundation" -Version 24.4.22295.22925
Start-NAVAppDataUpgrade -ServerInstance BC240 -Name "Base Application" -Version 24.4.22295.22925 -SkipVersionCheck
Start-NAVAppDataUpgrade -ServerInstance BC240 -Name "Application" -Version 24.4.22295.22925 -SkipVersionCheck
 
Any idea how to fix it.
Thanks

    Hi Varun, I encountered the same error during a migration from NAV2016 to BC24.4
    I solved the issue by populating the "Id" field via SQL in the "Company" table. It is sufficient to insert random GUIDs in this field
    Regards

    Hello,

    Thanks for sharing the details of your upgrade process.

    The error "An item with the same key has already been added" typically indicates a duplicate GUID or object reference in the upgrade path, often caused by:

    • Conflicting extensions or apps already installed with overlapping keys.
    • A corrupted or incomplete uninstall of a previous version.
    • A mismatch in the upgrade sequence or skipped dependencies.

    Here are a few suggestions to resolve it:

    1. Check for duplicate app entries in the NAV App Management tables using PowerShell or SQL.
    2. Uninstall and clean up any residual apps before re-running the upgrade commands.
    3. Make sure you're using the correct version syntax and that all dependencies (System Application, Business Foundation, Base Application) are properly aligned.
    4. Try running the upgrade with -Force and -SkipVerification flags if applicable, but only after confirming the environment is safe.

    Also, verify that the System Application is not already installed with the same key in another tenant or company context.

    Let me know if this helps!
