Using Cognos BI 8.3
All system: packages, cubes, reports, rules, profiles was build when we used namespace "Cognos Series 7".
After adding new namespace and deleting namespace Cognos Series 7 we got a lot of problems, tried to resolve it and as result broke all )) also we don't have back up of system.
Is it possible to restore old namespace and settings after restore system database with log file?
