convertion from root-relative to document-relative....

Newbe here. I have read many post regarding this matter, and I now
know my mistake in using root-relative links, but can I fix it?

I desire to have this section of my website be both its own domain,
and buried one directory deep in another domain. (in otherwords a
website, and a mirror within a folder in another website)

If I had built the site with document relative links I could upload
the site in any folder and it would work, correct?

Now, what do I do. It will take 6 hours to rebuild the site. It is
built with templates and library items, with lots of unique text links
within body copy. Plus some absolute links sprinkled everywhere.

Here it is in all its awful glory
