[wix-users] Need Advise on Upgrade

[Edwin Castro]

Your new unbundled MSIs should upgrade the MSIs bundled in your
bootstrapper. I expect that to work normally. Your old bootstrapper will
still be "installed" and you'll need to tell it to uninstall itself to
unregister itself. When you do that it will uninstall any bundled MSIs that
are still installed so you'll want to be careful.

Suppose you have a bundle B that includes MSIs A and C. If you upgrade MSI
A to MSI A1 but do not also upgrade C to a newer version, then B will be
installed/registered and C will be installed but MSI A will no longer be
installed as A1 removed A during upgrade. If you uninstall bundle B now,
then it will leave MSI A1 installed but will uninstall MSI C. To avoid that
you'd need to also upgrade MSI C to a newer version. And no matter how you
go about it, something will need to uninstall bundle B after you've
upgraded all the new separate MSI.
