2. Copy the following files from the ASP. net mvc 3 project to the corresponding location of your asp. Net MVC 2 project. You will need to update all references to the jquery library to modify the name of the new library (jQuery-1.5.1.js) [jquery used in MVC, with the version number, bringing some trouble to the provincial upgrade ]:

·/Views/Web. config

·/Packages. config

·/Scripts/*. js

·/Content/themes /*.*

 

3. In the root directory of the ASP. net mvc 3 project solutionPackagesCopy the folder to the root directory of your solution (in the directory where the. sln file is located.
