BuddyPress.org

I’ve an alternative that I can replace register.php code of buddypress in order to sign up through my earlier registration page.
But I don’t think it’s the right way, please suggest me that how can I stop using buddypress registration and profile page.
As, I already do have registration and profile page.
I want to use that only. My earlier registration page ” http://www.ferie.nu/wp-login.php?action=register” which is redirecting to register page of buddy press.

It’s very urgent so please reply on it with proper updates.

Thanks in advance
