I try to Migrate a SharePoint 2003 (WSS 3.0) to SharePoint 2010. I do it with the detach database method.
After I run the test-spcontentdatabase to the restored contentdatabase. I get some errors like that
Category : MissingFeature Error : True UpgradeBlocking : False Message : Database [WSS_CONTENT_SP30] has reference(s) to a missing feature: Id = [448e1394-5e76-44b4-9e1c-169b7a389a1b]. Remedy : The feature with Id 448e1394-5e76-44b4-9e1c-169b7a389a1b is referenced in the database [WSS_CONTENT_SP30], but is not installed on the current farm. The missing feature may cause up grade to fail. Please install any solution which contains the feature and restart upgrade if necessary.
Then I looked into the FEATURES Folder and copy the correspondending features (folders with the containing xml files) into the SharePoint 2010 FEATURES Folder.
After the I run the test again. But I got the same Warnings. Must I activate the copied features manually by myself? Or what did I wrong?
