[wix-users] Replacing old cached bundle.exe

Hi everyone,
I've installed version 1 with an old installer (using burn) - that doesn't support upgrades (and silent uninstallation)
I've created a new installer for version 2 that supports both.

Now I want to (somehow?) upgrade a computer that installed v1 to v2 without uninstalling v1.
I thought about replacing the cached burn.exe at "C:\ProgramData\Package Cache\{GUID}\Burn.exe" but that causes weird behavior (entry is not updated accordingly at Programs and Features, can't uninstall later, etc.)

Is there a way to do this?
What can I do to switch the old cached installer?
Do I need to make sure it has the old version number? (1?)

Thanks in advance,

Roni (Aron) Fuchs
