Abhishek,
That is a mighty wide ranger of versions... Here is what I found on the SAP site:
http://go.sap.com/product/data-mgmt/sybase-ase.item_2.html
These are the platforms that the product currently runs on. I assume ASE 15.7 and ASE 16.0
For older platforms, you can contact you local SAP Salesman for the Product Compatibility Matrix for each specific version.
ASE 12.0, 15.0 and 15.5 are still in production in some places but they are EOLed so I am not sure it is really worth finding out.
Regards,
Jean-Pierre
