Hi, I have Cognos 7.0 Impromptu reports and these reports have been created with the Mainframe datasource. Now the business needs these reports should be upgraded but with Oracle datasource. So what's the idea, first we should migrate these reports into ReportNet? then in that case what we will do with the Impromptu Catalog? Second, suppose we need to migrate these reports into Cognos 8 (may be 8.4) then how we will do that? do we need to create a FM Model for these reports. Please advice!
