Hi Vinocalk,
The Citrix iApp should create and implement a Citrix remote desktop profile when replacing Web interface servers and using APM (answer yes to question "Will you be using APM or Edge Gateway to securely proxy application traffic and authenticate users into your Citrix environment?", and yes to question "Do you want to replace Citrix Web Interface servers with the BIG-IP system?"). This setup uses F5's dynamic webtops to display available published applications rather then Citrix's web interface server. Also, there is a newer iApp located on devcentral which include support for Xendesktop 7 and storefront if you are interested.
