Migration from JSFv1.0 to JSF v1.1 in RSA v7.0

Hi,

I am into portlet(JSR168 portlet) develpment and very new to Richfaces componenets which we can implement in the JSF.
I know that richfaces supports from JSF v1.1 but in my environment I have only JSF v1.0,
I have developed some richface components and ran it on Websphere Application Sever 6.1, its working fine but I have to run it on WPS v6.0.
WAS v6.0 supports only JSFv1.0 runtime resources but WPS v6.0 internally uses WAS v6.0 not WAS v6.1 and I have the following questions:

1. How to migrate from JSF v1.0 to JSF v1.1 in RSA v7.0?
2. How to setup the JSF runtime (to support JSFv1.1) in WAS v6.0?

My Environment: RSA 7.0, WPS v6.0 (WAS v6.0), JSR168 Portlet(JSF portlets)

Pls advise me,

Regards
