[wix-users] How WixTools manage the upgrades?

[Davide Perini]

I like the "uninstall the old and install the new" but how can I create 
an exe file that does this with JPackage?
I am creating the exe with this command:

jpackage -i ../target --main-class org.duff.JavaFXStarter --main-jar 
duff-jar-with-dependencies.jar --icon ../data/img/duff.ico --win-menu 
--win-menu-group duff --copyright "duff" --name "myname" --vendor 
myvendor --win-dir-chooser --win-shortcut --win-per-user-install

How can I tell to "uninstall and install"?

Thanks,
Davide
