How to apply update on base setup?

[kalyani1217]

I have a base setup and I am able to create upgrades and patches for it. When we install an upgrade on the base setup, the base setup is uninstalled, and the upgrade is installed. In the upgrade, I can remove features from the base setup and add new features.

When we apply a patch to the base setup, the patch is installed. If we uninstall the patch, the system reverts to the previous version. With patches, I cannot remove features from the base setup, but I can add new features.

Is there any way to apply an update to the base setup? When I apply an update, the base setup should not be uninstalled. When I uninstall an update, it reverts to the previous version. In the update, I also want to be able to remove existing features from the base setup and add new features. I'm using WiX v3.14
