NOOOOOOOOOOO!!!!!!!!!
NEVER install a major system on top of another. You MUST back up (or clone) your 10.5, initialize-erase your startup drive and do a CLEAN INSTALL of 10.6 Snow Leopard. It's perfectly fine of course to put 10.5.7 on top of 10.5.6, but never 10.6.x on 10.5.8 etc. There are too many significantly different system components, which if not properly removed by the OSX 10.6 installer, will cause serious troubles. (quadrupley true this time with Apple's total system rewrite of Snow Leopard)
Maybe this is why I still hear stories of crashy computers, even in 2010!!!
Also, Apple, for the first time, seems to be even hiding clean installs. The Snow Leopard installer directs you more than ever to simply install 10.6 on top of 10.5.x.
Maybe it's ok now to install 10.6 on top of 10.5.x on the average home system. Not if your running a professional DAW that MUST run perfectly day in day out. Be safe, install conservatively. A computer is an extremely complex system and needs for things like installations to be done a certain and correct way. Also, contrary to popular opinion, setting up and maintaining a professionally used 24/7/365 DAW money making DAW is not for the interns to figure out as they go. It simply is not for the inexperienced or even lightly experienced.
No, as always on a pro workstation, you should:
1) research to make sure all you need runs on Snow Leopard 10.6
2) backup existing 10.5.x startup hard drive
3) erase (initialize) hard drive
4) clean install Leopard 10.6 and then run 10.6.3 updater (not 10.6.4, save the 10.6.4 updater for if ever you have an OS problem in the future...updaters can iron problems out often)
5) install PTHD 8.0.4 or 8.1cs2
If you want to be super perfect, I have started to run Diskwarrior on the boot-startup drive after ever major component install to definitely improved results.
-Install 10.6.0 and restart to 10.6.0
-restart to external drive and run Diskwarrior on boot-startup drive (it will find lots of errors)
-Install 10.6.3
-restart to external drive and run Diskwarrior on boot-startup drive
-Install PT 8
-restart to external drive and run Diskwarrior on boot-startup drive
-Install PT 8.1cs2 and 3rd party plugins (all check if up to date versions)
-restart to external drive and run Diskwarrior on boot-startup drive
