Cognos 7.4 Migration to Cognos8.4

[techicognos]

Anyone,

Im working with my company to migrate cognos 7.4 reports (IMR, IWR) and powerplay reports to cognos 8.4 env. After reading some documentation, i came to know we dont need to migrate Cube models but what are the options i have to migrate from 7.4 to 8.4?

would it be really possible to migrate PP reports?If so, how can i?

Any documentation to this would be highly appreciated.

Thanks in Advance.

For your Impromptu Cats and Reports, save yourself the head ache and start from scratch. Just IMHO.
