Wix installer CopyFile move file not working

I want to move a file from one Directory to another and it simply does nothing.

Here is the part from my Product.wxs:

<Feature Id="ProductFeature" Title="$(var.ProductName)" Level="1">
  <ComponentRef Id="testCopy"/>
</Feature>

<DirectoryRef Id="dirConfigs">
  <Component Id="web.config" Guid="8736259D-4FEE-4826-B109-76DD3B0EDAE7">
    <CopyFile Id="CopyWebConfig" 
              SourceProperty="dirProject"
              SourceName="Web.config"
              DestinationProperty="dirConfigs"
              DestinationName="Web.config"
              />
  </Component>
</DirectoryRef>

<Directory Id="TARGETDIR" Name="SourceDir">
  <Directory Id="$(var.PlatformProgramFilesFolder)">
    <Directory Id="dirParent" Name="$(var.CustomerName)">
      <Directory Id="dirProject" Name="$(var.ProductName)">
        <Directory Id="dirConfigs" Name="$(var.ConfigFolderName)">
        </Directory>
      </Directory>
    </Directory>
  </Directory>
</Directory>

Edit I also tried with Source/DestinationDirectory instead of Source/DestinationProperty Any ideas? Thanks in advance!
