Using ASP.NET in existing ASP site

[Jalinder]

The site on which I regularly work is in asp. Nothing's broke, so I'd keep all existing pages as is in asp. But for new pages I would like to shift to ASP.NET.
My questions are:
If I add one single .aspx file in the asp site, will it work?
Will new .aspx files affect existing site in anyway? Especially will there be any effect on session state of asp pages?
Will the session get passed between .asp and .aspx files?
Any other issues?

yes, you can run asp and asp.net side by side

>Will the session get passed between .asp and .aspx files?
