Do you necessarily need two separate apps? If you create a .NET 2.0 "Web Application Project" (vs. a "Website Project") you can pretty much cut-and-paste all the files from App_One into App_Two's project, recompile, and you'll have a converted app that you can easily extend!

BoulderBum you r absolutely right but App_One is huge application and client is not ready to pay for the breaking changes required to migrate from 1.1 to 2.0 and also being an insurance application it run 24X7 and client is not ready for downtime and on the contrary the client wants the next phase to be developed with in 2.0 or 3.0
The only challenge is how to share the session across the application.

I see. Well, what you'll probably want to do is craft your own session state provider that has logic to resolve who your user is when they're browsing back and forth on the sites.

These two articles should get you started.

If they're going to let you use .NET 3.0 (which is really just extensions for 2.0, not a new version), and you are currently using In-Proc session state (which implies a single processor) then I'd consider having the back-end of the session state provider use a WCF service over IPC to maximize performance, while abstracting out a common service that each app's provider instance can call.

Can i get all the session variables of App_One in my App_Two by writting the custom session state provider in App_Two and without disturbing the App_One.

The only thing you'd need to do to App_One is drop your session state provider into App_One's bin (or the GAC) and add a few lines of the web.config file. None of the code would change, and you wouldn't need to recompile/redeploy.

Any code referencing Session (e.g. "Session["MyVar"] = 1;") would then use your session state provider as the data store.

Adding the line to the web.config will restart the ASP.NET process and kill any active sessions, but having that minimimal amount of downtime is far, far preferable to any sort of solution where you try to hack the existing session state (which would be more complicated, less elegant, less secure, and potentially be unstable).
