To upgrade an existing version of Business Insight with the latest version, complete the following procedures on the computer where Business Insight is installed. Before you begin, create a backup of your content store. If you are going to install a newer version of Cognos on the same machine as your existing version, either shutdown your legacy system or adjust the port settings to avoid port conflicts.
There are two options for upgrading Cognos. If you are running incrementals on your INOW database such that all User IDs are retained, you will want to upgrade the existing content store. This will retain all reports and report permissions. If during the upgrade your User IDs will change, a better option is to start from a new content store and import any reports you want to keep from your legacy system.
