How to Verify an Upgrade?
Is there a tool to verify that an upgrade occurred properly? I have encountered a few issues where a clean install works correctly but upgrades from previous versions causes problems. Some of these problems are due to unintended behaviour (i.e. a bug) in a previous installer.
Basically I would like to compare a portion of the filesystem, registry and the IIS configuration from a system that had a clean install performed verses various upgrade scenarios.
The validation during building will bring up some issues that may help. However, I am not aware of an external program that does this. Perhaps other people will know of something.
