We are not not able to convert MOSS 2007 Standard to MOSS 2007 Enterprise. The key is a valid one.

I'm wondering if you already had a MOSS 2007 Enterprise installation but didn't know it. (Idea comes from "already exists under the parent ") SP 2010 "FAQ" (mainly useful links): http://wssv4faq.mindsharp.com/default.aspx WSS3/MOSS FAQ (FAQ and Links) http://wssv3faq.mindsharp.com/default.aspx Both also have links to extensive book lists and to (free) on-line chapters

Easy test.....try and enable enterprise features. If it works, you have enterprise already.

Yes and No. Although it's difficult to find these days, there once was a download of a Trial edition and when that was installed it was possible to decide between Standard and Enterprise. However the trial period would have expired a long time ago if the Trial edition was downloaded and immediately installed, so this objection is only if the trial file was downloaded but then saved for a year or two before being used. Not therefore too likely.SP 2010 "FAQ" (mainly useful links): http://wssv4faq.mindsharp.com/default.aspx WSS3/MOSS FAQ (FAQ and Links) http://wssv3faq.mindsharp.com/default.aspx Both also have links to extensive book lists and to (free) on-line chapters

Sorry guys... I was on Vacation. Thanks for the replies Back to the issue. The enterprise license is not activated.

Central Administration > Operations > Timer Job Definitions >Removed Trial Conversion Job Restarted the WSS Timer service (In the Services MMC) Restarted IIS Ran configuration wizard again. Central Administration > Operations > Convert License Type And it worked !!!
