Uninstall InstallShield Before Running Wix Install

[KMarois]

I am building a Wix project as a replacement for an Installshield project. Is it possible to have Wix uninstall the previous InstallShield install first?

Would setting the UpgradeCode to the GUID in InstallShield do the trick?

Thanks

If the UpgradeCode matches, and the new WiX version is higher - an update should uninstall the installshield msi.

If you are talking about a WixProject just to create an Msi (or did you mean something like a Burn bootstrapping application?)
