Business content for Investment Management & Travel management

Hi All,

I am trying to install Business content for Investment Management & Travel management, I found the content in 3.x flow with Infosource. once I raised with SAP they also reply with 3.5 flow. I am doubt full to build with 3.5 flow because 3.5 flow SAP support date over on 31.03.2013. SO how they will support. Please put some light if some one have any idea.

Cheers
Anil
