I'm using WiX 3.7's Burn/Managed Bootstrapper Application features to create a custom MBA-based installer. For each of the packages in my bundle's chain, when performing a MinorUpdate, I can easily detect which of the package features are already installed to ensure I maintain those feature selections during the upgrade by using these events provided in the WiX base class for the bootstrapper: DetectPackageComplete, DetectMsiFeature, DetectRelatedBundle, DetectRelatedMsiPackage, DetectComplete.
However, during a MajorUpgrade, I'm only seeing a way to determine which package(s) are installed, but am not seeing how to determine which features are installed, as the DetectMsiFeature event does not fire. I tried using the MigrateFeatures flag on the product's configuration, but that doesn't seem to work (or I'm not using it right).
What is the correct way to detect/migrate existing features when performing a MajorUpgrade using a Custom Managed Bootstrapper Application in WiX?
Some file snippets:
Note: I can provide a fully working VS Solution with all code if that is helpful.

Output on upgrade:
Note that the package and two features were both installed at v1.0.0 and detected in state Absent. The Related Package was detected, but no feature details are included.

DetectMsiFeature is telling you the state of features for the new package; it's not installed, so obviously the features aren't. DetectRelatedMsiPackage gives you the data you need to query the feature states of the installed version using the (native) MSI API functions MsiEnumFeatures and MsiGetFeatureState/MsiGetFeatureUsage.
I'm marking Bob Arnson's response as the answer, since it gave me what I needed to push this along, but for others who come across this post, I thought I'd give a little more detail about how you can gather the feature states using the WiX-provided ProductInstallation class (found in the Microsoft.Deployment.WindowsInstaller.dll assembly, which is in the WiX SDK), thus removing the need to make your own direct calls to native MSI API.
Here's an example of a method that could be registered to the DetectRelatedMsiPackage event. Note that you'll need to store off the information you gather so that you can set the appropriate states during the Plan phase.
private void DetectRelatedMsiPackageHandler(object sender, DetectRelatedMsiPackageEventArgs e)
{
var existingPackageProductCode = e.ProductCode;
var actionToBeAppliedToExistingPackage = e.Operation;
var existingPackageId = e.PackageId;
var existingPackageVersion = e.Version;
Log(string.Format("Detected existing related package {0} (product: {1}) at version {2}, which will be {3}",
existingPackageId, existingPackageProductCode, existingPackageVersion,
actionToBeAppliedToExistingPackage));
if (actionToBeAppliedToExistingPackage == RelatedOperation.MajorUpgrade)
{
//requires reference to WiX Toolset\SDK\Microsoft.Deployment.WindowsInstaller.dll
var installedPackage = new Microsoft.Deployment.WindowsInstaller.ProductInstallation(existingPackageProductCode);
if (!installedPackage.IsInstalled) {
Log(string.Format("Migrating Package {0}, which is not installed, so marking it and it's features as Absent", existingPackageId));
//TODO: add logic to store state so that during Plan phase can set package with package with product code = existingPackageProductCode to PackageState.Absent
} else {
Log(string.Format("Migrating features for MajorUpgrade of Package {0}", existingPackageId));
foreach (var currentInstallFeature in installedPackage.Features) {
if (currentInstallFeature.State == InstallState.Local) {
Log(string.Format("Migrating feature {1} of Package {0} - marking as Present", existingPackageId, currentInstallFeature.FeatureName));
//TODO: add logic to store state so that during Plan phase can set package and feature states based on this info
} else {
Log(string.Format("Migrating feature {1} of Package {0} - marking as Absent", existingPackageId, currentInstallFeature.FeatureName));
//TODO: add logic to store state so that during Plan phase can set package and feature states based on this info
}
}
}
}
}
