I currently work for a company that uses a combination of ASP.NET Webforms and legacy ASP pages for web development. This works fairly well for their current projects but I would like to convince / suggest to them to switch over to ASP.NET MVC since most of their codebase consists of wiring form elements to stored procedure parameters. Just using an ORM is also a possibility but I think it would be a good idea to use this opportunity to switch to an MVC framework.
However, I'm not sure how easy it will be to deploy an ASP.NET MVC app along side ASP.NET and Classic ASP code while the codebase is updated. First, I would like to ask if this is even possible. I've seen threads about running ASP.NET with Classic ASP and ASP.NET MVC with Webforms but not all three in the same application. They currently have Webforms and Classic ASP working together so the pitfalls associated with that are already solved. Second, what are some strong selling points that would help me convince the rest of the team that learning a new framework and converting existing code will be worth it in the long run?
