@sgayathri we are in the process of upgrading to Cognos 11. You should be contacted about the upgrade at some point. All I can say is that the interface of Cognos is changing considerably and there will be some slight changes to navigating around Cognos. I don't have any dates. We will be providing resources to help our customers transition from Cognos 10 to Cognos 11. As for feature changes for Cognos 10, there haven't been any.
