I'm trying to migrate our existing TFS 2008/SharePoint installation to TFS 2012/SharePoint 2010. If I do it without SharePoint it all works OK, but if I try and include SharePoint it fails.
At the moment I'm starting from scratch and including SharePoint.
I've run the Configure Extensions for SharePoint Products Wizard, restored the TFS 2008 databases, run STSADM from the command line, and now I'm attempting to run the TFS 2012 Upgrade Wizard: it fails at the, Configure the Server Running SharePoint step with the error "TF250004: The SharePoint Products installation is either corrupt or is not valid. Verify that SharePoint Products is a supported version and is functioning properly, and then try again."
Can someone please advise me what I've done wrong?
