Copy a solution in visual studio 2005

I have a working solution, and I would like to copy it and paste in a new folder. I am creating a new version of the site, and w开发者_开发技巧ant to build on a "copy" of the solution. But when I do it, all the paths are lost and it doesn't work. What am I missing. What is the process to copy a working solution and get it to work from new location?

Copy the solution and the related projects. If the paths don't work then edit the SLN with a text editor to fix the paths.
