After double checking the [FAQ](https://stackoverflow.com/faq)'s to be sure this is an alright question here, I've got a perhaps simple question about the CMS Typo3.

The title puts it quite literally, but I'll elaborate what I have, what I'm thinking about doing, and what I'd like to achieve.

What I have is access to a Linux server via the good ol' ssh PuTTy. Newest versions of everything right down the PHP in the Apache installation. I've also already installed one Typo3 on it, via the "Introduction Package". 

What I'm thinking about is the fact I've already made some changes (this first installation has been my sandbox to learn in, though it's still quite confusing and all of the documentation is "old"). 

What I'd like to achieve is simple. I'd like to export a site that is about 80% developed from our partner client and possibly import it to a "new installation" of Typo3, thus leaving the 2 completely in tact.

My question comes before my attempt due to my concern as to how this may affect any Apache or PHP files (such as the ini). I'd like to know if anyone has tried this and/or knows of any possible "cons" in attempting such maneuver. 

In a similar area, I've one other question, my Intro Pack does not seem to have an "Import" tab?

I've a lot of other questions, but I'll save them for an expert or possibly other post here on SO. For now, if anyone has any info on dual installations, I'd be much obliged.
