Hopefully someone here can help me out. We're having problems upgrading our 2007 farm to 2010 (using the database attach method on a new 2010 farm) and all the problems seem to be related to artifacts left behind by a CKS installation.
We installed CKS (Enhanced Blog Edition) a long time ago on our farm for the blogging capabilities until we discovered the problems associated with CKS and publishing sites. We uninstalled the product according to the documentation (ie. undeploy, detract
solution etc.) and everything seemed to be removed successfully. Now we have come to upgrade our farm to Sharepoint 2010 and we are getting lots of errors referencing features related to CKS, for example one error found by running test-spcontent database is
below (real database name replaced by our-database) :
Category : MissingSetupFile
Error : True
UpgradeBlocking : False
Message : File [Features\CKS EBE Themes\Themes\Intensive\images\Technorati.png] is referenced  times in the database [our-database], but is not installed on the current farm. Please install any feature/solution which contains
Remedy : One or more setup files are referenced in the database [our-database], but are not installed on the current farm. Please install any feature or solution which contains these files.
There are quite a few instances of similar errors in the log referring to different components of CKS.
I've hunted for any references to these features using enumsolutions and Sharepoint Manager 2007 but am unable to find them to get rid of them. Has anyone come across this problem and managed to fix it or can someone give me a clue where to start?
