text: We are upgrading from Cognos 8.2 to 10.2.1. We have taken a cold back-up of our Content Store Cognos 8 database and it has been successfully upgraded to 10.2.1. When we log on to the Cognos portal in 10, we can see all Public reports/folders/packages, however under the My Folders tab, all content is missing.
  We are using Active Directory for Authentication in Cognos 10.2.1. The namespace is different from that of Cognos 8. I can see the old Cognos 8 namespace in Cognos 10.2.1, but it is inactive.
  Do we need to have the same namespace ID/names in both versions in order to see the My Folders content in Cognos 10? If so, how do I go about this? We didn't use Active Directory in Cognos 8, the server itself provided the authentication.
  Do I reconfigure the namespace from Cognos8 in Cognos 10? If so, how will Cognos know which namespace to use at run-time?
  Any advice/help would be much appreciated!
