DWALogin and redirect

Hi all,

Im upgrading from Lotus Domino 8.5.3 to IBM Domino 9.0.1. Im done fixing databse view and upgrade mail template. the only one left is when I restart back HTTP server, the login form and redirect design still remain same as 8.5.3. Do I need to remove old iwaredir.nsf and create new iwaredir.nsf ? or just use compact command to update the design?

thanks in advance~ :)
