The unanimous verdict is that it's no problem whatsoever, aside from 
obvious things like not letting the install program access the second 
disk and accidently newfs partitions on it. I should also point out my 
choice of words wasn't the best when I posed the original question - I 
meant to say *install* Solaris 9 over the Solaris 8 system, not 
*upgrade* Sol8 -> Sol9. No matter - it's still ok for Solaris 9 to read 
Solaris 8 formatted file systems

Thanks again to those who responded!
