Rest assured, SAS has placed a priority on ensuring connectivity between SAS V9 environments and SAS Viya environments. We're working on technical material to help explain the way you'd handle such actions as accessing and transferring data, moving models, promoting reports, and remotely executing code between the two environments.
That said, the SAS Viya Early Preview program is designed to be used solely with the supplied sample data and code. It is not intended to support data transfer or access outside of the SAS-hosted environment. Existing SAS customers can apply to the free trial program of the SAS Viya Data Mining and Machine Learning product. You'll find a link to that form at the bottom of the main SAS Viya page (sas.com/viya). These free trial environments can be installed at your site, and thus leverage your data, including that from a V9 environment.
As you've noted, the programming interface for the Early Preview program is indeed a modified version of SAS Studio. The Early Preview is intended as a test drive of the new SAS Viya Data Mining and Machine Learning analytic tasks/actions offered using this interface.
