Check this link,
Please have a look in the 'SAP ERP Solution Browser' (Customer tool to identify new features and functions with focus on SAP ERP )
http://solutionbrowser.erp.sap.fmpmedia.com/
There you can define the 'Source/Target' Release Versions and the delta functionality will be available.
There is lot difference between 4.6c and 6.0
ecc 6.0 coming with inbuild webdynpro , BSP it is not 4.6c
In ecc we have interactive forms concept where it was not there in 4.6c
4.6c there is no unicode concept here we have unicode and non unicode
From the ABAP perspective,
The WS_* function modules used in 4.6c has become obsolete from 4.7C. All the WS_* FMs have been replaced by GUI_* FMs.
(ii) Concept of Unicode is introduced.
(iii) Few tables have been modified in ECC6.0.
Tables TVARV & TTREX have been replaced by TVARVC & TTREXN respectively.
