How to 'Save As' my entire VB.Net solution in VS2003

I have developed an application in VB.Net (in V.Studio2003).  Let's call this application 'Version1'.
I now wish to enhance the application (the end result of which will be called, strangely enough, 'Version2').
I want to preserve Version1 exactly as it is right now, so that any development/enhancements I make to the application will be reflected only in Version2.  Version 1 will remain as it was before I did any such development work.

How do I safely 'Save As' my Version1 solution to a new 'Version2'...?.  Or do I need to 'Save As' the Project?  Or should I simply copy the entire folder containing Version1 and simply rename the folder, solution and project files to 'Version2'...?

I know this is a reasonably simple question, but is there anything I need to specifically watch for when trying to copy Solutions in this way?  I don't want any of the enhancements to affect any of the *.vb files that relate to Version1.

You will have to do a save as on each file in the project.   Just double click on the file then select file save as [whatever]
Just do this in Windows Explorer:

Version1 - MyProject
Version2 - MyProject

I don't think that this is good idea to keep different versions of the same program with different names, so simplest way is the best.

BTW, if you use program like PVCS, SourceSafe etc, it allows to keep different versions of projects.

Like AlexFM said:

You might use sourcesafe-> check in your version 1 into sourcesafe.
go to your sourcesafe-> locate your project -> right click 'label'
type something like 'version 1'

from now on, these specific versions can be fetched if you check out from that version

If you want parallel development, it will be different, but according to your description you only want straight evolution.
What you also can do: use copy in windows :D put it in a zipfile or so and call it Version 1.. but I'd prefer the sourcesafe option.
