[SunHELP] From Solaris 2.6 to 8 : Upgrade or Fresh Install

[DAUBIGNE Sebastien - BOR ( SDaubigne@bordeaux-bersol.sema.slb.com )]

I plan to move a server (E6500) from Solaris 2.6 to Solaris 8 (64 bits).

What do you recommend :
-	Upgrade Solaris 2.6 using Sun upgrade procedure (with LU or simply
with the installation CD), then upgrade other software not supported under
Solaris 8 ?
-	Make a fresh install on a new disk, then install all other software
on it ?

My fear is that Sun upgrade could leave unnecessary files in various
directories or legacy config options (/etc/system or others). 
So I'm more confident with a clean fresh install, but I'm open to any
advice.

I will summarize.
