So I have a site that I created and I had used a portal alias something like dnn.dwi.com/catalog.  What i want to do is put that site onto the url dwi.com.  I know I can create a new portal alias, but how do i get all that stuff from the 'test' site onto this new one?

I actually don't have to move any files between servers.  All my stuff is on the live server right now, it's just that I want my info to be shown on a different URL.  For example, I've been working on dnn.diversifiedwoodcrafts.com/catalog (which is live) and I want to move all that stuff to www.diversifiedwoodcrafts.com.  I didn't think i needed to back anything up because i'm not moving files any place.  They should be staying exactly where they are because it is live.  All I need is to switch the URL (or portal alias?) for the site.

I don't know if it's something where i have to make the "test" site a template and then create a new portal alias and then when i create that site, just use that 'test' template?

So I took my test site and created a template from that portal.  I created a new portal with my main URL that is already live with an old version of the site (there has been content on this site for a long time now).  But now I want this site to point to my new portal alias i just created so that same URL shows the new information and new site I've been working on.  How do I do this?  Do I need to point IIS to something?  If so, what?  I'm a little confused on this part.
