    If you install Evaluation edition of Windows Server it will expect a Retail key when doing the straight conversion. For those of us with Volume license keys the upgrade path involves first using DISM ONLINE Set edition using a KMS key, Then on reboot use slmgr /ipk using your Volume key and then finally run slmgr /ato.

    You can get the KMS keys here:

    For example

    DISM /Online /Set-Edition:ServerStandard /ProductKey:N69G4-B89J2-4G8F4-WWYCC-J464C /AcceptEula

    After reboot then


    then activate

    slmgr /ato

    If that doesn't work, you have to reinstall 2019 with the NON EVAL ISO.

    Hope above information can help you.

    What channel is the product key? Should be retail in order to activate the evaluation.

    I'd get in touch with the seller about this. The burden is on them to provide access to licensed installation media for the products they sell.
