I've found many different variations of this question, but nothing that seems to be exactly what I'm trying to attempt, so please excuse me if it has already been answered.
I have an old WebForms solution that I have completed converted to MVC 4 (C#). I have both projects in separate solutions. I want to completely remove the old WebForms project, solution, and deployed files and redeploy the new MVC 4 site in it's place. That being the case, I don't want to kill all the old URLs. For example, in the WebForms site you could go to:
http://mysite.com/Customers.aspx
in MVC 4, that URL is now:
I would like to setup a Route or a Redirect rule that handles scenarios like that. I'm even fine adding many rules manually as the site really isn't that big. I feel like this should be pretty straightforward, but I'm really new to this space and just can't quite seem to figure out where or what I should be adding.
