When upgrading from a standard SKU to an Enterprise SKU in SharePoint (MOSS 2007), things can (and do) go wrong. Come to think of it, I’ve never seen one complete successfully without some type of manual intervention. Fortunately, the majority of errors that are experienced are recoverable. Take for instance:
An existing request to enable the Enterprise feature is in progress. To check the status of this request, go to the Timer Job Status page in Central Administration Operations and check the status of the Office Server Enterprise Features Upgrade Job.
When you find the job in the Timer Job Status page, you will see that it needs to run on all servers in your farm. Chances are it has failed on one (or more) servers. The quick fix? Restart (or start if stopped) the Windows SharePoint Services Timer service on the server where the upgrade job failed. After the job has completed, return to Central Administration to verify that your farm has been upgraded.
It went bad back when we did our North America farm too. You know what I did, of course. What else, reboot all the boxes in the farm!
Brilliant!!
