upgrading a 32bit msi to a 64bit msi


We are using Advanced Installer to create an MSI installation. The app was previously set as 32-bit package (in Installation Options).
As part of an upgrade, the executables contained in the app were made x64 compatible, but we left the app as 32-bit package by mistake, and several x64 devices were installed with it.

If we now change the MSI to x64 package, would it upgrade the previous 32-bit installation successfully? Are there any issues we should consider?

If the resources were all market as 64-bit in the 32-bit installer, I think the upgrade should work just fine.
