problem in using AJAX

i am using visual web developer 2005 and SQL Express 2005 with VB as the code behind

i have created a web site using ASP.NET Web Site installed template

now i want to add AJAX to my web site .

i have downloaded the AJAX December CTP and installed and it is working fine with newly created website using the ASP.NET AJAX CTP-Enabled WebSite template

is it possible to convert my existing web site to use AJAX or should i do it from the beginning

please help me

You can convert the website to use Ajax from an Atlas CTP. This guide should help.
