Is it a feasible option to use Genesis for this integration?
I didn't find any pointers about it.
Is genesis used only for integration of SiteCatalyst with other Products?
Cui Meng your answer give me some good info.
Currently Genesis is only used to import/export data between SiteCatalyst and other products, including Salesforce. You can find the brief introduction about Genesis http://tv.adobe.com/watch/omniture-products-overview/what-is-genesis/
