I'm planning a project that needs a Sybase upgrade from 11.0.3 to 12 in HP-UX. I have some questions because I haven't experience in Sybase.

* How many versions are between Sybase 11.0.3 and Sybase 12.0?
* How much complex is the upgrade process? My worry is about object structures (tables, views...) more that access questions.

Thanks a lot!
