Microsoft SharePoint 2007 - Fixing a failed WSS v3 and/or MOSS 2007 SP1/Infrastructure Patch Upgrade

The Upgrade Process
I was upgrading an environment (MOSS version 12.0.0.4815) in the following manner:

1. Check all Timer jobs have run to completion in the existing environment
2. Check no errors with WSP
3. Install WSS v3 SP1 Patch (Skip Configuration wizard)
4. Install MOSS 2007 SP1 Patch (Skip Configuration wizard)
5. Install WSS v3 infrastructure Patch (Skip Configuration wizard)
6. Install MOSS 2007 infrastructure Patch
7. Following the prompts for the Configuration Wizard (PSconfigUI).

Okay, so far so good.

The Problems
In the middle of the configuration wizard, it seemed to have stayed on Step 5 for hours. Looking at the Event Viewer, errors with messages:

“Content index on Search could not be initialized. Error The content index is corrupt. 0xc0041800.Component: bd72df39-396a-472f-8a1a-db6c3241e922”



Checking Upgrade.log (in 12\Logs\), unveiled some Exception errors.

The Solution
So then I cancelled out of the setup (which took a while to cancel – actually it didn’t cancel until I ran the following command), and ran the following command to force the upgrade of the SharePoint environment:

psconfig -cmd upgrade -force



Checked the version numbers and the existing sites I had - That seemed to have fixed my issues


Alternative
Alternatively, the stsadm utility can be used (though I didn't have to use it):

stsadm -o upgrade -forceupgrade
