Hey Rajveer! I created a blog post series on how I recently architected a multi-site solution using MVC Areas: https://www.cjsharp.com/blog/2021/01/04/multi-site-episerver-solutions-using-mvc-areas/. Without knowing what the current codebase looks like and without knowing how you are curring using MVC areas, take that blog post with a grain of salt, and use it as a general guide. :) In most cases, you shouldn't have any issues using MVC Areas to separate out a site. I think the most important part to make this work is setting the RouteData.DataTokens["area"] value in the OnActionExecuting() filter method, and it should be set to the name of your Area. You'll also notice in the blog post that you don't need MVC's out-of-the-box area routing that's generated in the RegisterArea() method.
