Renaming Root folder of a project

Can anyone help me with this issue? We are working with Sitefinity 3.5 community. It is the CMS that runs on our Aptify Ebusiness platform. We hired a contractor to help us build out a test server. He installed Sitefinity and took a copy of our current 'production' project and added it to 'C:\Program Files (x86)\telerik\Sitefinity3.5 Community\Websites' within a folder called 'Ebusiness'. He configured IIS and added the project to system with the Sitefinity Project Manager. All runs well and we began developing additional content.
Later on, it became apparent that the 'root' folder under ...Sitefinity3.5 Community\Websites was named incorrectly. Our production server has ...Sitefinity3.5 Community\Websites\Ebusiness50\... rather than ...Sitefinity3.5 Community\Websites\Ebusiness\... I have been meticulously looking through the knowledge base to find out how to 'rename' the folder.  I am familiar with the IIS configuration of the 'virtual folder', but cannot find how to modify Sitefinity to 'see' the new location. I am sure that I am missing something very obvious. Anybody?
