SAP Portal 7.4 compatibility with webdynpro abap 7.02

Hi all,

I had a portal 7.0 and a SAP SRM 7.02 EHP2.

We were installed a new portal 7.4 and we have transported all content of our portal 7.0 to the portal 7.4.

In the portal we are calling a several webdynpro Abap (SRM 7.02) the wendynpro abap work correctly but the problem is with the visualization. For example with the style(color and shape) of tabs.

New portal:
