Where do I include the Upgrade/Target Image in the following Patch XML? I need to include the Validate ProductId element which is why I cannot use my previous XML structure.

<Patch AllowRemoval="yes"
    Classification="Update"
    Comments="Patch"
    Description="Patch"
    DisplayName="Patch"
    Manufacturer="..."
    MoreInfoURL="http://..."
    TargetProductName="Szenario Rechner"
    Codepage="1252">

    <Media Id="1000"
           Cabinet="Patch.cab"
           EmbedCab="yes"
           Source="Cab1" >
        <PatchBaseline Id="RTM">
            <Validate ProductId="no" />
        </PatchBaseline>
    </Media>
    <PatchFamily Id='pf1'
                 Version='1.2.7.0'
                 Supersede='yes'>

        <ComponentRef Id="Szenariorechner" />
    </PatchFamily>
</Patch>

Below is my previous patch XML.

    Your old patch authoring refers to the patch creation using Patch Creation Properties. The one you are referencing as a new uses purely WiX. As you can see, UpgradeImage/TargetImage pairs are not required for the later one.

    Instead, you should author a TargetProductCodes element directly under the Patch root and add a number of TargetProductCode elements as its direct children:

    <TargetProductCodes>
   <TargetProductCode Id="PUT-PRODUCT-CODE-HERE" />
   <TargetProductCode Id="PUT-PRODUCT-CODE-HERE" />
   <TargetProductCode Id="PUT-PRODUCT-CODE-HERE" />
   ...
   <TargetProductCode Id="PUT-PRODUCT-CODE-HERE" />
</TargetProductCodes>

    When you build a patch, you feed the torch.exe with both base and updated MSI (or WIXPDB) files to generate a diff. Hope it’s helpful. I suggest you to look through the “purely WiX” approach once again to understand it better.
