How to migrate Powerplay local client reports to Cognos 10?

I have Powerplay local client reports (.ppx format) against local cubes and trying to understand the migration path for moving the reports to Cognos 10.

If I understand correctly there is a macro (as part of the Powerplay client installation) to convert .ppx reports to Cognos 10 Powerplay reports, but this applies only for reports that access remote cubes.

Any help would be appreciated.
