Generally, it's always a good idea to do a clean install of a new OS. Although you can usually just do an upgrade, this will eventually lead to problems. The conventional wisdom is that you should never upgrade in the middle of a project. If I had to be finished with all ongoing projects before doing an upgrade, I'd still be on OS 8. But if you clone your startup drive BEFORE doing the clean install, you can always return your system to it's previous state if there's a problem.
Here's the user tip about cloning your startup drive
And as per StudioX
Here's the way I do a clean install -- erase the drive- install the OS- run updates on the OS until there are no more- repair permissions using Disk Utility- Insert the FCS disk- Run FCS installer- repailr permissions using Disk Utility- Run Software updater until there are no more updates- repair permissionsBe sure ....1. DO NOT change the default installation settings for either OSX or FCS2. If you have issues running the software, remove all externalconnections leaving only the keyboard. mouse and monitor.

For people interested in a more complicated but perhaps better way.
"This multi-part tutorial suggests a long term strategy designed to produce a problem-free install, and a quick reinstall if problems should arise again — with the proviso that you spend a one time spare afternoon preparing the necessary files and materials. The strategy is intended to produce long term results and far less down time."
And a note on installing fcp6 in Lion (not sure about mountain lion or Mavericks). But first, be aware that fcp6 and 7 are no longer in development and do not be surprised if you see problems when working with them on Lion or Mountain Lion. This is not from personal experience rather this is from past experience. The older your apps, the more likely you'll have problems running them on newer OS's.
And now to return to our previously scheduled program:
You'll either need to install rosetta from your snowleopard install disk (I've done this several times for clients and it has worked fine although there is one person on this forum who insists that this is a dangerous procedure. Do some searching her for Rosetta and you'll see many threads discussing this issue.)
or use this technique
(which I haven't done).
And here's Nick Holmes take on installing both FCP7 and FCPX on the same system:
You must install FCP 7 first and then run all updates.
Install FCP X last. If you already have FCP X on your system, use this tool to remove it:http://www.digitalrebellion.com/fcsremover/ and download X again once FCP 7 is installed. You won't have to pay again, the App Store knows that you already bought it.
The FCS suite is automatically moved to a folder within Applications during the FCP X install. I just left mine there and updated my Dock.
